Equilibrium Question 597
Question: For the following reaction in gaseous phase $ CO+\frac{1}{2}O_2\to CO_2 $ ; $ K_{p}/K_{c} $ is [DCE 2002]
Options:
A) $ {{(RT)}^{1/2}} $
B) $ {{(RT)}^{-1/2}} $
C) $ (RT) $
D) $ {{(RT)}^{-1}} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ K_{p}=K_{c}{{[RT]}^{\Delta n_{g}}} $
$ \Delta n_{g}=1-1.5=-0.5 $
$ K_{p}=K_{c}{{[RT]}^{-1/2}} $
$ \therefore \frac{K_{p}}{K_{c}}={{[RT]}^{-1/2}} $
