Chapter 15, Problem 44E

Interpretation Introduction

Interpretation:

The equilibrium expression for each of the given chemical equation is to be written.

Concept Introduction:

Equilibrium may be defined as a state in which the rate of forward reaction is equal to the rate of backward reaction.

The expression of equilibrium is the ratio of concentration of product to the concentration of reactant.

$K_{\text{eq}}\text{= }\frac{\left[\text{Product}\right]}{\left[\text{Reactant}\right]}$

Here, $\left[\text{Product}\right]$ is a concentration of product and $\left[\text{Reactant}\right]$ is a concentration of reactant.
