Equilibrium Question 555
Question: In which one of the following gaseous equilibria $ K_{p} $ is less than $ K_{c} $ [EAMCET 1989; MP PET 1994; Pb. PMT 2000; KCET 2001; CBSE PMT 2002]
Options:
A) $ N_2O_4 $ ⇌ $ 2NO_2 $
B) $ 2HI $ ⇌ $ H_2+I_2 $
C) $ 2SO_2+O_2 $ ⇌ $ 2SO_3 $
D) $ N_2+O_2 $ ⇌ $ 2NO $
Show Answer
Answer:
Correct Answer: C
Solution:
$ K_{p}=K_{c}{{(RT)}^{\Delta n}} $
$ \Delta n=-1 $ for reaction $ 2SO_2+O_2 $ ⇌ $ 2SO_3 $ So for this reaction $ K_{p} $ is less than $ K_{c} $ .
