Chapter 15, Problem 15.94SP

Interpretation Introduction

Interpretation:

The concentration of ${\text{NO, N}}_{\text{2}}{\text{,O}}_{\text{2}}$ at the equilibrium condition needs to be determined.

Concept introduction:

A chemical reaction is said to be in equilibrium if there is no further change in its concentration takes place with time. The equilibrium constant is defined as ratio of equilibrium concentration/molarity of product to reactant reaction raised to the power of the respective stochiometric coefficient in the equilibrium reaction.

For a general equilibrium reaction as follows:

$aA+bB\rightleftharpoons cC+dD$

The expression for equilibrium constant can be represented as follows:

$K_c=\frac{{\left[C\right]}^c{\left[D\right]}^d}{{\left[A\right]}^a{\left[B\right]}^b}$

Here, A, B, C, D is concentrations of reactants and products and a, b, c, d is the respective stoichiometric coefficient.
