Chapter 15, Problem 2SAQ

Interpretation Introduction

Interpretation:

The equilibrium constant for reaction is K_c = 1.0×10³, mixture at A(g)⇄B(g). Concentration of B in the mixture should be determined.

Concept introduction:

For the reaction type:

xA+yB⇄mC+nD

where A, B, C and D represent chemical species and x, y, m and n are coefficients of the balanced chemical equation. The equilibrium constant for such reactions are given as:

${\text{K}}_{\text{a}}=\frac{{\left[\text{C}\right]}^{\text{m}}{\left[\text{D}\right]}^{\text{n}}}{{\left[\text{A}\right]}^{\text{x}}{\left[\text{B}\right]}^{\text{y}}}$

The square brackets represent concentration of the species in equilibrium.
