Chapter 13.6, Problem 13.10P

(a)

Interpretation Introduction

Interpretation:

Thedirection in which the given reaction moves has to be predicted. Also determine the reaction mixture is at equilibrium or not.

Concept introduction:

Reaction quotient (Q) is the ratio of product of concentration of products to that of product of concentration of reactants, raised to the power of coefficients.

Consider a reaction

$\text{aA + bB}\stackrel{}{\rightleftharpoons }\text{cC + dD}$

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

Where,

a, b, c and d are coefficients of each species.

t is arbitrary time for measuring concentration .
