Chapter 12, Problem 40QRT

Interpretation Introduction

Interpretation:

The equilibrium constant of the given reaction, ${\text{N}}_{\text{2}}{\text{O}}_{\text{4(g)}}\stackrel{}{\rightleftharpoons }{\text{ 2NO}}_{\text{2(g)}}$ has to be calculated.

Concept Introduction:

Equilibrium constant:

At equilibrium the ratio of products to reactants (each raised to the power corresponding to its stoichiometric coefficient) has a constant value, K

For a general reaction,

  $\text{aA+bB}\rightleftarrows \text{cC+dD}$

  $\text{Equilibrium}\text{constant}\text{K}\text{=}\frac{{\left[\text{C}\right]}^{\text{c}}{\left[\text{D}\right]}^{\text{d}}}{{\left[\text{A}\right]}^{\text{a}}{\left[\text{B}\right]}^{\text{b}}}$
