Equilibrium Question 558

Question: In which of the following reaction $ K_{p}>K_{c} $ [AFMC 1995]

Options:

A) $ N_2+3H_2 $ ⇌ $ 2NH_3 $

B) $ H_2+I_2 $ ⇌ $ 2HI $

C) $ PCl_3+Cl_2 $ ⇌ $ PCl_5 $

D) $ 2SO_3 $ ⇌ $ O_2+2SO_2 $

Show Answer

Answer:

Correct Answer: D

Solution:

For reaction $ 2SO_3 $ ⇌ $ O_2+2SO_2 $

$ \Delta n $ is + ve so $ K_{p} $ is more than $ K_{c} $ . By $ K_{p}=K_{c}{{(RT)}^{\Delta n}} $
