An aqueous reaction occurs by a two-step mechanism,shown below. Step 1: A₂X₂ + Y → A₂X + XY
Step 2: A₂X₂ + XY → A₂X + X₂ + Y
What is the catalyst in this reaction?

Question

An aqueous reaction occurs by a two-step mechanism,shown below. Step 1: A₂X₂ + Y → A₂X + XY Step 2: A₂X₂ + XY → A₂X + X₂ + Y What is the catalyst in this reaction?

Quizplus · Accepted Answer

A catalyst is a substance that is consumed and then regenerated in the reaction mechanism. In this mechanism, Y is consumed in Step 1 and regenerated in Step 2, making it the catalyst.
