Chapter 19, Problem 19.50P

Interpretation Introduction

Interpretation:

Whether the given reaction under given conditions is at equilibrium or not has to be given.  If not, the direction to which the reaction will proceed to attain equilibrium has to be given.

Concept Introduction:

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

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

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

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