Q.
The value of equilibrium constant for the reaction 2A(ag)+B(ag)⇌2C(aq) is 4 mole -1 lit . At the given time of equilibrium if the reaction mixture has the concentrations [A]=0.2 mole.lit -1;[B]=0.1 mole.lit -1 and [C]=0.3 mole.lit -1 then the relation between reaction quotient, equilibrium constant and the direction of reaction is
