Chapter 17, Problem 57A

Interpretation Introduction

Interpretation:

The meaning of the statement that chemical equilibrium is a dynamic process has to be explained.

Concept Introduction:

Equilibrium:

It is defined as a state in which two opposite processes are balanced. Like forward and backward reaction. The reaction in which reactant convert into product is known as forward reaction while the reaction in which product changes into reactant is known as backward reaction.

Answer to Problem 57A

The statement that chemical equilibrium is a dynamic process, means that in equilibrium the concentration remains constant as when the product is forming, the reactant also formed at the backward reaction. And the rate at which this is happening is same.

Explanation of Solution

Forward reaction: The reaction in which reactant convert into product is known as forward reaction.

Backward reaction:The reaction in which product changes into reactant is known as backward reaction.

Equilibrium:

In equilibrium, the forward and backward reaction occurs simultaneously. It means that reactant convert into product and product changes back into reactant. And the concentration remains constant as when the product is forming, the reactant also formed at the backward reaction and the rate at which this is happening is same.
