Chapter 15, Problem 62E

Interpretation Introduction

Interpretation: The table is to be completed by filling the missing values of $\left[{\text{H}}_{\text{2}}\right]$, $\left[{\text{I}}_{\text{2}}\right]$, $\left[\text{HI}\right]$ and $K_{\text{eq}}$.

Concept Introduction:

The equilibrium constant is the ratio of concentration of product to the concentration of reactant with their stoichiometric coefficient.

$K_{\text{eq}}=\frac{\left[\text{product}\right]}{\left[\text{reactant}\right]}$

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

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