Chemical Equilibrium.docx

Chemical Equilibrium chemical equilibrium is defined as the state where there is no further change in the concentration of the reactants or products.

Types of Chemical Equilibrium Homogeneous equilibrium: In an equilibrium reaction when both the product and the reactants are present in the same phase, it is called as homogeneous equilibrium. For example, N2(g) + 2SO2(g) + O2(g) ⇋ 2SO3 (g)

⇋

3H2(g)

2NH3

(g)

Heterogeneous equilibrium: In an equilibrium reaction when both the product and the reactants are present in a different phase, it is called as homogeneous equilibrium. For example, H2O(l) CaCO3(s) ⇋ CaO(s) + CO2(g)

⇋

H20(g)
