Chapter 5, Problem 5.38E

Interpretation Introduction

Interpretation:

The ClF will form or it under goes decomposing has to be given.

  $C{l}_2\left(g\right)+F_2\left(g\right)\rightleftharpoons 2ClF\left(g\right),K_C=20$

Concept introduction:

Comparison of ${\text{Q}}_{\text{c}}{\text{ and K}}_{\text{c}}$ :

When ${\text{Q}}_{\text{c}}{\text{ < K}}_{\text{c}}$, the reaction will proceed in right direction, $\text{reactants}\stackrel{}{\to }\text{products}$

When ${\text{Q}}_{\text{c}}{\text{ > K}}_{\text{c}}$, the reaction will proceed in left direction, $\text{reactants}\stackrel{}{\leftarrow }\text{products}$

When ${\text{Q}}_{\text{c}}{\text{ = K}}_{\text{c}}$, the reaction will remain unchanged, $\text{reactants}\rightleftharpoons \text{products}$
