2NH 3 (g) + 
O 2 (g) 
2NO (g) + 3H 2 O (g) is___x10 -33 (Nearest integer)
Text Solution
Verified by ExpertsThe correct answer is:
4
(4)
N 2 (g) + 3H 2 (g) 
2NH 3 (g),K 1 =4x10 5 ...(i)
N 2 (g) + O 2 (g) 
2NO(g),K 2 = 1.6 x 10 12 ...(ii)
H 2 (g) + 
O 2 (g) 
H 2 O(g), K 3 = 1.0 x 10 -13 ...(iii)
(ii) + 3x(iii)-(i)
2NH 3 (g) + 
O 2 (g) 
2NO(g) + 3H 2 O(g)
