What factors does equilibrium depend on?

Equilibrium constant depends on temperature and is independent of the actual quantities of reactants and products, the presence of a catalyst and the presence of inert material. It is also independent of concentrations, pressures and volumes of reactants and products.

What are the 3 factors that can change the equilibrium of a system?

Three types of stresses can alter the composition of an equilibrium system: adding or removing reactants or products, changing the total pressure or volume, and changing the temperature of the system.

What does reaction equilibrium depend on?

Composition of the Equilibrium State Depends on the ratio of the forward- and reverse rate constants. Be sure you understand the difference between the rate of a reaction and a rate constant.

What are the 3 stresses to equilibrium?

The three most common ways to stress a system at equilibrium are changing the concentration of one of the reactants or products, changing the temperature of the system, or changing the pressure on the system.

What are the 4 requirements for an equilibrium system?

Terms in this set (4)
  • Rate forward = Rate reverse.
  • Closed System: no reactants or products lost.
  • all appears constant (no VISIBLE changes)
  • DYNAMIC (moving)- changing on ATOMIC level.

What are the 3 components of general equilibrium analysis?

Data, theory, and shocks are the three basic elements of a CGE study, and combined they determine the results. The results of a CGE analysis are numerical 'predictions' of the changes in the economic system.

What are the main condition of equilibrium?

Conditions of Equilibrium

An object is in equilibrium in a reference coordinate system when all external forces (including moments) acting on it are balanced. This means that the net result of all the external forces and moments acting on this object is zero.

What are the conditions necessary for equilibrium quizlet?

The necessary and sufficient condition(s) for an object to be in equilibrium can be described as: The sum of all forces acting on the object is equal to zero and the sum of all moments acting on the object is equal to zero.

Does equilibrium depend on concentration?

Equilibrium constants are not changed if you change the concentrations of things present in the equilibrium. The only thing that changes an equilibrium constant is a change of temperature. The position of equilibrium is changed if you change the concentration of something present in the mixture.

Does equilibrium depend on temperature?

Increasing the temperature decreases the value of the equilibrium constant. Where the forward reaction is endothermic, increasing the temperature increases the value of the equilibrium constant.

What factors do not affect equilibrium?

A catalyst does not affect the chemical equilibrium. It only speeds up a reaction. In fact, catalyst equally speeds up the forward as well as the reverse reaction.

What factors does equilibrium depend on? (2023)
What are the types of equilibrium process?

Homogeneous equilibria – In these types of equilibrium reactants and products are found in same phase. Heterogeneous equilibria – In these types of equilibrium reactants and products are found in different phases.

How does pressure affect equilibrium?

When there is an increase in pressure, the equilibrium will shift towards the side of the reaction with fewer moles of gas. When there is a decrease in pressure, the equilibrium will shift towards the side of the reaction with more moles of gas.

Which are examples of equilibrium?

A few examples of equilibrium are:
  • A book kept on a table at rest.
  • A car moving with a constant velocity.
  • A chemical reaction where the rates of forward reaction and backward reaction are the same.

What are three characteristics of equilibrium?

The three characteristics of equilibrium are:
  • The forward rate and the reverse rate should be the same.
  • The value of the equilibrium constant does not change at a given temperature but changes as the value of temperature changes.
  • There is no effect on equilibrium by the use of catalyst.

Which are examples of equilibrium quizlet?

The development of a vapor pressure above a liquid in a closed container is an example of a physical equilibrium.

What are the two types of equilibrium in economics?

The types of economic equilibrium include microeconomic and macroeconomic. In microeconomics, supply and demand between buyers and sellers are balanced. With macroeconomics, an economy achieves a balance of aggregate demand and supply. Competitive prices are an integral part of the theory.

What are the assumptions of equilibrium?

General Equilibrium Assumptions

All productive services units are similar. The income of the consumers is constant and given. The productions techniques have no change. The production factors go through mobility between different occupations and places.

What are the conditions of equilibrium in macroeconomics?

Macroeconomic equilibrium is a condition in the economy in which the quantity of aggregate demand equals the quantity of aggregate supply. If there are changes in either aggregate demand or aggregate supply, you could also see a change in price, unemployment, and inflation.

Which is one of the most important condition for equilibrium?

  • The first condition of equilibrium states that for an object to remain in equilibrium, the net external force acting upon it in all directions must be zero.
  • Any object which is in equilibrium should not experience any linear or angular acceleration.

What is the equilibrium condition of reaction?

chemical equilibrium, condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs. A reversible chemical reaction is one in which the products, as soon as they are formed, react to produce the original reactants.

Which of the following conditions is true about equilibrium?

Amounts of reactants and products are equal.

Which of the following must be true at equilibrium?

A body is in equilibrium only when there is no net external force acting on it. So, in other words, the sum of all forces acting on it must be zero for a body to be in equilibrium.

What is required for equilibrium chemistry?

Equilibrium is achieved when the forward rate of a reaction is equal to the reverse rate of a reaction. This very simple principle can be observed in a closed container of liquid.

How does volume affect equilibrium?

Conversely, if you decrease the pressure (by increasing the volume of the container), equilibrium will shift to favor the side with the most moles of gas, since more moles will occupy a greater volume.

Why does heat affect equilibrium?

By adding more heat, equilibrium will shift to use up the additional heat, thus favoring this forward direction.

Is equilibrium independent of temperature?

Temperature Dependence of the Equilibrium Constant. Assuming ΔH° and ΔS° are temperature independent, for an exothermic reaction (ΔH° < 0), the magnitude of K decreases with increasing temperature, whereas for an endothermic reaction (ΔH° > 0), the magnitude of K increases with increasing temperature.

How does low temperature affect equilibrium?

Decreasing the temperature shifts the equilibrium in the direction of the exothermic reaction. This reduces the effects of the change because, during an exothermic reaction, energy is transferred to the surroundings. If given, the energy change for a reversible reaction is always for the forward reaction.

What factors affect equilibrium in economics?

A decrease in demand will cause the equilibrium price to fall; quantity supplied will decrease. An increase in supply, all other things unchanged, will cause the equilibrium price to fall; quantity demanded will increase. A decrease in supply will cause the equilibrium price to rise; quantity demanded will decrease.

What are the 5 conditions for equilibrium?

In order for a population to be in Hardy-Weinberg equilibrium, or a non-evolving state, it must meet five major assumptions:
  • No mutation. No new alleles are generated by mutation, nor are genes duplicated or deleted.
  • Random mating. ...
  • No gene flow. ...
  • Very large population size. ...
  • No natural selection.

What are 3 characteristics of equilibrium?

The three characteristics of equilibrium are:
  • The forward rate and the reverse rate should be the same.
  • The value of the equilibrium constant does not change at a given temperature but changes as the value of temperature changes.
  • There is no effect on equilibrium by the use of catalyst.

What is needed to achieve equilibrium?

Section Summary

The first condition necessary to achieve equilibrium is that the net external force on the system must be zero, so that F = 0.
