Equilibrium Question 574
Question: In which of the following case Kp is less than Kc [AFMC 1997; Pb. PMT 2000]
Options:
A) $ H_2+Cl_2 $ ⇌ $ 2HCl $
B) $ 2SO_2+O_2 $ ⇌ $ 2SO_3 $
C) $ N_2+O_2 $ ⇌ $ 2NO $
D) $ PCl_5 $ ⇌ $ PCl_3+Cl_2 $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \underset{3}{\mathop{2SO_2}},+O_2 $ ⇌ $ \underset{2}{\mathop{2SO_3}}, $ for this reaction $ \Delta n $ = -1 ; \ $ K_{c}>K_{p} $
