Interpretation: The effect of a catalyst on the collisions between molecules is to be explained.
Concept introduction: A catalyst increases the speed of both forward and backward reactions to the same extent, allowing the system to achieve equilibrium faster. The presence of catalysts does not influence the equilibrium position.
Answer to Problem 99A
Catalysts have no effect on collision frequency, but they can increase the frequency of successful collisions.
Explanation of Solution
Catalysts are substances that speed up the rate at which a
