(a)

Interpretation Introduction

Interpretation:

The reaction has to be balanced and the reaction quotient, ${\text{Q}}_{\text{c}}$ for the given reaction, ${\text{C}}_{\text{2}}{\text{H}}_{\text{6}}{}_{\text{(g)}}{\text{ + O}}_{\text{2(g)}}\stackrel{}{\rightleftharpoons }{\text{ CO}}_2{}_{\text{(g)}}{\text{ + H}}_{\text{2}}{\text{O}}_{\text{(g)}}$ has to be written.

Concept Introduction:

Reaction Quotient:

Reaction quotient, ${\text{Q}}_{\text{c}}$ is the ratio between product of the product concentration to the product of the reactant concentration with each term raised to the power of its balancing coefficient.

Consider a general equation,

  $a\text{A +}b\text{A}\stackrel{}{\rightleftharpoons }c\text{C}+d\text{D}$

Where a, b, c and d are the stoichiometric coefficients.  The reaction quotient is,

  ${\text{Q}}_{\text{c}}\text{ = }\frac{{\text{[C]}}^{\text{c}}{\text{[D]}}^{\text{d}}}{{[\text{A]}}^{\text{a}}{\text{[B]}}^{\text{b}}}$

(b)

Interpretation Introduction

Interpretation:

The reaction has to be balanced and the reaction quotient, ${\text{Q}}_{\text{c}}$ for the given reaction, ${\text{CH}}_{\text{4}}{}_{\text{(g)}}{\text{ + F}}_{\text{2(g)}}\stackrel{}{\rightleftharpoons }{\text{ CF}}_4{}_{\text{(g)}}{\text{ + HF}}_{\text{(g)}}$ has to be written.
