The equilibrium constants of the following are N 3H 2NH ;K N O 2NO;K H O H O;K The equilibrium constant (K) of the reaction : K 2NH O 2NO 3H O will be (NEET 2017) (a) K K K (b) K K K (c) K K K (d) K K K
Answer
A
Explanation
From the given equations, 3 2 2 1 1 2NH N 3H ; K ….(i) 2 2 2 N O 2NO; K ….(ii) 3 2 2 2 3 3 3H O 3H O; K 2 ….(iii) By adding equations (i), (ii) and (iii), we get K 3 2 2 3 2 3 1 5 2NH O 2NO 3H O, 2 K K K K
