The reaction quotient (Q) for the reaction N (g) 3H (g) 2NH (g) is given by [NH ] Q . [N ][H ] (CBSE Med. 2003) The reaction will proceed from right to left if

The given reaction is: 2 2 3 N (g) 3H (g) 2NH (g) Reaction constant for the reaction will be 2 3 3 2 2 [NH ] Q= [N ][H ] The given reaction will proceed in the backward direction when the value of the reaction quotient will be greater than the value of the equilibrium constant i.e., c Q > K The concentration of the product is more than the value of equilibrium and the concentration of the reactant is less than the value of equilibrium. Hence, the correct answer is option (c) CHEMICAL EQUILIBRIUM 55
