A reaction with reaction quotient Qc and equilibrium constant `K_(c)^(+)`, will proceed in the direction of the products when-

At equilibrium the reaction quotient is greater than equilibrium constant.

What is the difference between reaction quotient (Q) and equilibrium constant (K) of a reaction?

What is meant by reaction quotient, Q_c ?

Assertion : If reaction quotient, Q_(c) for a particular reaction is greater than K_(c) the reaction will proceed in the direction of reactants. Reason : Reaction quotient is defined in the same way as the equilibrium constant K_(c) except that the concentrations in Q_(c) are not necessarily equilibrium values.
