Question

Explain homogeneous and heterogeneous equilibrium giving examples

Answer 1

If all the reactants and products present in an equilibrium mixture are in same 

phase → homogeneous equilibrium. 

Example: N_2(g) + 3H_2(g)  ⇌ 2NH_3(g)

If all the reactants and products present in an equilibrium mixture are indifferent phase → heterogeneous equilibrium. 

Example: CaCO_{3 (s)} ⇌ CaO_(s) + CO_2(g)
