How can you predict the following stages of a reaction by comparing the value of ?
(i) Net reaction proceeds in the forward direction.
(ii) Net reaction proceeds in the backward direction.
(iii) No net reaction occurs.
The values of (the equilibrium constant) and (the reaction quotient) less than or greater than one another decides the direction in which reaction will proceed as follows-
(i) As , this implies that in order to reach the equilibrium, the concentration of the products must be increased, hence the reaction will proceed in the forward direction.
(ii) If , this implies that in order to reach the equilibrium, the concentration of the products must be decreased, hence the reaction will proceed in the backward direction.
(iii) If , no net reaction occurs as the equilibrium has been achieved.
