Solution: Consider the following reaction: 2H 2O2(aq) → 2 H2O(l) + O2(g)When 1.0 g of KI is added to the H 2O2, bubbles of O 2 are produced at an increased rate. When the reaction is complete, the mass of KI is 1.0 g. The KI is a A. ProductB. CatalystC. ReactantD. Reaction Intermediate

Problem

Consider the following reaction: 2H 2O2(aq) → 2 H2O(l) + O2(g)

When 1.0 g of KI is added to the H 2O2, bubbles of O 2 are produced at an increased rate. When the reaction is complete, the mass of KI is 1.0 g. The KI is a 

A. Product

B. Catalyst

C. Reactant

D. Reaction Intermediate
