Equilibrium Question 785
Question: The ratio $ \frac{K_{p}}{K_{c}} $ for the reaction $ CO(g)+\frac{1}{2}O_2(g)\rightarrow CO_2(g) $ is:
Options:
A) $ \frac{1}{\sqrt{RT}} $
B) $ {{(RT)}^{1/2}} $
C) RT
D) 1
Show Answer
Answer:
Correct Answer: A
Solution:
$ K_{p}=K_{C}{{(RT)}^{\Delta n}}; $ For the reaction $ CO(g)+\frac{1}{2}O_2(g)\rightarrow CO_2(g) $
$ \Delta n_{g}=1-( 1+\frac{1}{2} )=-\frac{1}{2} $
$ \therefore K_{p}=\frac{K_{C}}{\sqrt{RT}};,\frac{K_{p}}{K_{C}}=\frac{1}{\sqrt{RT}} $
