Q. In which of the following reactions, the concentration of reactant is equal to concentration of product at equilibrium: (K = equilibrium constant)

EAMCETEAMCET 2004Equilibrium

Solution:

Concentration of reactant and product becomes equal at equilibrium only when the value of equilibrium constant is one. $ \underset{(R)}{\mathop{\text{Reactant}}}\,\underset{(P)}{\mathop{\text{Product}}}\, $ $ {{K}_{c}}=\frac{[Product]}{[Reactant]} $ If the concentration of both reactants and products becomes equal, then the value of $ {{K}_{c}}=1. $
