Chapter 6, Problem 15E

Interpretation Introduction

Interpretation:Illustration amongst the snapshots that first represents an equilibrium mixture should be identified and number of ${\text{A}}_{\text{2}}\text{B}$ placed initially in container should be determined,

Concept introduction:Le Chatelier’s established the qualitative effects of change in concentration or partial pressure of reactant on reaction equilibrium.

It suggests that if a certain change in concentration of substrates occurs then reaction proceeds so as to minimize the effects of changes. This way the direction of equilibrium can be altered by various changes and yield of the desired product can be enhanced. For example, the Le Chatelier’s has improved the synthesis of ${\text{NH}}_{\text{3}}$ by Haber’s process.

The equilibrium constant is function of temperature and nature of reactants or products while equilibrium position can be attained in several possible pathways and is independent of any one set of conditions.
