(a)

Interpretation Introduction

Interpretation:

The rate of the hydrogen gas evolution will be increased, decreased, or unchanged with the given information has to be stated.

Concept introduction:

Reaction: Substances which are mutually involved each other in a chemical process and changed into different substances.

Rate of reaction: It represents the speed at which a chemical reaction runs.  How much concentration of reactants consumed and how much concentration of product formed in a unit of time is said to be rate of reaction.
