(a)

Interpretation Introduction

Interpretation:

In a reaction of passing steam over hot carbon, ${\text{C}}_{\text{(s)}}{\text{ + H}}_{\text{2}}{\text{O}}_{\text{(g)}}\stackrel{}{\rightleftharpoons }{\text{CO}}_{\text{(g)}}{\text{ + H}}_{\text{2(g)}}$ what happens to $\text{[CO]}$ when carbon is added has to be predicted.

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, $\text{reactants}\stackrel{}{\rightleftharpoons }\text{products}$
