Chapter 18.3, Problem 30LC

Interpretation Introduction

Interpretation: The expression for the rate of a chemical reaction is to be stated.

Concept Introduction: The reaction in which the rate of the forward reaction is equal to the rate of the backward reaction is called an equilibrium reaction.

Answer to Problem 30LC

The amount of products is larger in a $\left({\text{K}}_{\text{eq}}=1\times {10}^8\right)$ in comparison to b $\left({\text{K}}_{\text{eq}}=3\times {10}^{-6}\right)$ .

Explanation of Solution

The equilibrium constant value tells whether there is more amount of a product or reactant at equilibrium for the given reaction. The larger the value of the equilibrium constant means the reaction mixture consists of mainly products at equilibrium. The smaller the value of the equilibrium constant means the reaction mixture consists of mainly reactants.

Thus, the amount of products is larger in a $\left({\text{K}}_{\text{eq}}=1\times {10}^8\right)$ in comparison to b $\left({\text{K}}_{\text{eq}}=3\times {10}^{-6}\right)$
