Equilibrium Question 704

Question: In which of the following equilibrium systems is the rate of the backward reaction favoured by increase of pressure [KCET 2001]

Options:

A) $ PCl_5 $ ⇌ $ PCl_3+Cl_2 $

B) $ 2SO_2+O_2 $ ⇌ $ 2SO_3 $

C) $ N_2+3H_2 $ ⇌ $ 2NH_3 $

D) $ N_2+O_2 $ ⇌ $ 2NO $

Show Answer

Answer:

Correct Answer: A

Solution:

The rate of backward reaction favoured by increase of pressure in the reaction as $ \Delta n $ is positive $ PCl_5 $ ⇌ $ PCl_3+Cl_2 $
