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 $
