Factors affecting Equilibrium position

Front

What is the position of equilibrium when H2O is added to the reaction CoCl4^2- + 6H2O ⇌ Co(H2O)6^2+ + 4Cl-?

Back

The position of equilibrium will shift to the right (and become more pink).

Front

Define the equilibrium constant.

Back

The equilibrium constant is a value that expresses the ratio of the concentrations of the products to the concentrations of the reactants at equilibrium for a chemical reaction.

Front

What are the three factors that affect the equilibrium of a reaction?

Back

Temperature, pressure, and concentration.

Front

What are the two factors to look for when determining if the reaction is at equilibrium?

Back

Forward and reverse reaction rates are equal and concentration is constant.

Front

What is Le Chatelier's Principle?

Back

Le Chatelier's Principle describes how chemical systems respond to external disturbances.

Front

What happens to the position of equilibrium if the concentration of reactants is increased?

Back

The position of equilibrium will shift to the right to favor the formation of products.

Front

How does temperature affect the position of equilibrium in an exothermic reaction?

Back

Increasing the temperature shifts the position of equilibrium to the left, favoring the reactants.

Front

What is the effect of increasing pressure on a reaction at equilibrium?

Back

Increasing pressure shifts the position of equilibrium towards the side with fewer moles of gas.

Front

What is the relationship between the rates of forward and reverse reactions at equilibrium?

Back

At equilibrium, the rates of the forward and reverse reactions are equal.

Front

What is the effect of adding a catalyst to a reaction at equilibrium?

Back

A catalyst speeds up both the forward and reverse reactions equally, but does not affect the position of equilibrium.
