Chapter 12, Problem 12.23PAE

Interpretation Introduction

Interpretation:

“Write the equilibrium constant expression for given reaction:

$C{H}_4(g)+2O_2(g)\rightleftarrows C{O}_2(g)+2H_{2}O(l)$, should be explained

Concept introduction:

• At equilibrium; the concentrations of reactants and products do not change according to time.
• At equilibrium; the concentrations of reactants and products remain constant.
• At equilibrium; the rate of forward reaction and the rate of reverse reaction are same.
• The equilibrium, where the physical state of reactants and products are same state is called homogeneous equilibrium.
• The equilibrium, where the state of reactants and products are different is called heterogeneous equilibrium.
• In the heterogeneous equilibrium, the value of equilibrium constant does not depend on the amounts of pure solids or liquids present.
• The fundamental reason for this behavior is that the concentration of pure solids and liquids cannot change.
