Chapter 12, Problem 12.108PAE

Interpretation Introduction

Interpretation: Equilibrium constant using thermodynamic data.

Conceptual Introduction: Equilibrium constant gives the relationship between product and reactant at equilibrium. It is ration of concentration of product to the concentration of reactant.

K > 1: Reaction is product favoured.

K < 1: Reaction is reactant favoured.

Parameters like temperature, pressure and ionic strength has effect on equilibrium constant.

Consider the following reaction: $\text{aA + bB }\rightleftharpoons \text{cC + dD}$

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