In which of the following reactions, an increase in the volume of the container will favour the formation of products?
A
4NH 3 (g) + 5O 2 (g) 
4NO (g) + 6H 2 O ( λ )
4NO (g) + 6H 2 O ( λ )
B
2NO 2 (g) 
2NO (g) + O 2 (g)
2NO (g) + O 2 (g)
C
3O 2 (g) 
2O 3 (g)
2O 3 (g)
D
H 2 (g) + I 2 (g) 
2HI (g)
2HI (g)
Text Solution
Verified by ExpertsThe correct answer is:
B
Volume P ↓ reaction proceed in which direction where number of gases mole increases.
2NO 2 (g) 
2NO(g) + O 2 (g)
n g = (2 + 1) – 2 = 1
