Chapter 18, Problem 31E

Interpretation Introduction

Interpretation:

The direction of the equilibrium for ${\text{4H}}_{\text{2}}\left(\text{g}\right)+{\text{CS}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons {\text{CH}}_{\text{4}}\left(\text{g}\right)+2{\text{H}}_{\text{2}}\text{S}\left(\text{g}\right)$ when system is enlarged is to be predicted.

Concept Introduction:

The equilibrium constant is a parameter which describes the relationship between concentration of the reactants and the products at equilibrium stage. Equilibrium constant of a reaction is expressed by the ratio of concentration of product species raised to the power of their stoichiometric coefficients to the concentration of reactant species raised to the power of their stoichiometric coefficients.
