Question

A reaction with reaction quotient Q_C and equilibrium constant K_C, will proceed in the direction of the products when

(a) Q_C = K_C

(b) Q_C < K_C

(c) Q_C > K_C

(d) Q_C = 0

Answer 1

Answer is : (b) Q_C < K_C

For an equilibrium reaction,

If Q_C = K_C,the reaction is in equilibrium.

If Q_C > K_C, the reaction proceeds in backward reaction.

If Q_C < K_C, the reaction proceeds in forward reaction.

Thus, the reaction will proceed in the direction of products i.e., forward reaction when Q_C < K_C.
