QAIPMT-2003-Ch-2704: NEET 2003 Chemistry - Class 11 AIPMT-2003-Ch-2704 Solution: The equilibrium constants of the following are \(N_2+3H_2…

The equilibrium constants of the following are

N_2+3H_2\rightleftharpoons 2NH_3; K_1

;

N_2+O_2\rightleftharpoons 2NO; K_2

;

H_2+\frac{1}{2}O_2\rightleftharpoons H_2O; K_3

. The equilibrium constant (K) of the reaction:

2NH_3+\frac{5}{2}O_2\rightleftharpoons 2NO+3H_2O

will be

Multiple Choice Options

A $K_2K_3^3/K_1$
B $K_2K_3/K_1$
C $K_2^3K_3/K_1$
D $K_1K_3^3/K_2$

Step-by-Step Verified Solution

2NH 3 _ N 2 + 3H 2 ; 1 K 1 N 2 + O 2 _ 2NO ; K 2 3H 2 + 3 2 O 2 _ 3H 2 O; (K 3 ) 3 By adding all equations, we get 2NH 3 + 5 2 O 2 _ 2NO + 3H 2 O _ K = K 2 _ ( K 3 ) 3 K 1
