Review Question 14.8

What role does a catalyst play in a reversible chemical reaction? How does a catalyst affect the value of the equilibrium constant for a reaction?


Catalysts increase the rate of a chemical reaction but do not affect the final composition of a reaction. Thus, a catalyst may change the rate at which dynamic equilibrium occurs but does not change the value of the equilibrium constant.
