Chapter 22, Problem 104IAE

Interpretation Introduction

Interpretation:

The concentration of $\left[{\text{Cl}}_{\text{2}}\right]\text{, }\left[\text{HOCl}\right]\text{, }\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]\text{ and }\left[{\text{Cl}}^{\text{-}}\right]$ with help of given ${\text{K}}_{\text{c}}$ value should be determined.

Concept introduction:

The equilibrium constant ${\text{K}}_{\text{c}}$ is the expression that indicates the ratio of concentrations of product and reactant molecules at equilibrium condition of the balance chemical equation. The concentration terms must be raised by power of number of moles given in the balance chemical equation.

$\begin{array}{l}{\text{aA}}_{\text{(g)}}{\text{+ bB}}_{\text{(g)}}\rightleftharpoons {\text{cC}}_{\text{(g)}}{\text{+ dD}}_{\text{(g)}}\\ \text{Kc =}\frac{{{\text{[C}}_{\text{(g)}}\text{]}}^{\text{c}}{\text{ [D}}_{\text{(g)}}{]}^{\text{d}}}{{{\text{[A}}_{\text{(g)}}\text{]}}^{\text{a}}{\text{ [B}}_{\text{(g)}}{]}^{\text{b}}}\end{array}$
