What are the types of chemical equilibrium?

Solution
There are two types of chemical equilibrium:
(i) Homogeneous equilibrium: It is that equilibrium reaction in which all the reactants and products are in the same phase. For example
left parenthesis straight i right parenthesis space straight H subscript 2 left parenthesis straight g right parenthesis space plus space straight I subscript 2 left parenthesis straight g right parenthesis space space space space space space space space rightwards harpoon over leftwards harpoon space space space space space 2 HI left parenthesis straight g right parenthesis left parenthesis ii right parenthesis space straight N subscript 2 left parenthesis straight g right parenthesis space plus space 3 straight H subscript 2 left parenthesis straight g right parenthesis space space space space space rightwards harpoon over leftwards harpoon space space space space 2 NH subscript 3 left parenthesis straight g right parenthesis left parenthesis iii right parenthesis space 2 SO subscript 2 left parenthesis straight g right parenthesis space plus space straight O subscript 2 left parenthesis straight g right parenthesis space space rightwards harpoon over leftwards harpoon space space space 2 SO subscript 3 left parenthesis straight g right parenthesis
(ii) Heterogeneous equilibrium: It is that equilibrium reaction in which reactants and products are present in two or more phases, e.g. 
left parenthesis straight i right parenthesis space 3 Fe left parenthesis straight s right parenthesis space plus space 4 straight H subscript 2 straight O left parenthesis straight g right parenthesis space space rightwards harpoon over leftwards harpoon space space space Fe subscript 3 straight O subscript 4 left parenthesis straight s right parenthesis space plus space 4 straight H subscript 2 left parenthesis straight s right parenthesis left parenthesis ii right parenthesis space straight C left parenthesis straight s right parenthesis space plus space straight H subscript 2 straight O left parenthesis straight g right parenthesis space space rightwards harpoon over leftwards harpoon space space space CO left parenthesis straight g right parenthesis space plus space straight H subscript 2 left parenthesis straight g right parenthesis left parenthesis iii right parenthesis space CaCO subscript 3 left parenthesis straight s right parenthesis space space space rightwards harpoon over leftwards harpoon space space space space space CO left parenthesis straight s right parenthesis space plus space CO subscript 2 left parenthesis straight g right parenthesis left parenthesis iv right parenthesis space space space Hgo left parenthesis straight s right parenthesis space space rightwards harpoon over leftwards harpoon space space Hg left parenthesis straight l right parenthesis space plus space 1 half straight O subscript 2 left parenthesis straight g right parenthesis
