Question

Give one example with balanced chemical equation of each of homogeneous and hetero geneous chemical equilibrium systems.

Answer 1

Example of homogeneous and heterogeneous equilibrium system are given below -

•Equilibrium system refers to the state where rate of forward reaction is equal to rate of backward reaction, thus maintaining equilibrium.

•Homogeneous reaction is the reaction where all the reactants and products are in same phase.

•Example of homogeneous reaction is - 2SO2 (g) + O2 (g) <=> 2SO3 (g)

•In the given reaction, all the components are in gas phase.

•Heterogeneous reaction is the reaction where products and reactants are in different phase.

•Example of heterogeneous reaction is - C (s) + O2 (g) <=> 2CO (g)

•In this reaction, reactant is in solid and gas phase and product is in gas phase.
