Solution
The correct option is C3Fe(s)+4H2O(g)⇌Fe3O4(s)+4H2(g) (a) and (b) are examples of homogeneous equilibrium as all the reactants and the products are in the same phase. (c) is clearly heterogeneous as the phases of all the reactants and the products are not same.
Theory:
Types of equilibrium on the basis of physical state : 1.Homogeneous equilibrium 2.Heterogenous equilibrium
Homogeneous equilibrium : In Homogeneous equilibrium all reactants and products are in the same phase. For ex: PCl5(g)⇋PCl3(g)+Cl2(g) Heterogeneous Equilibrium : In Heterogeneous equilibrium reactants and products are in two or more phases. For ex. :- CaCO3(s)⇋CaO(s)+CO2(g) and 3Fe(s)+4H2O(g)⇌Fe3O4(s)+4H2(g)
