Interpretation Introduction

Interpretation: “Calculate the equilibrium concentration of ammonia; for given reaction; $N_2(g)+3H_2(g)\rightleftarrows 2N{H}_3(g)$, 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.
