Question

$K_p/K_c$ for the reaction, $CO\left(g\right)+\frac{1}{2}{O}_2\left(g\right)\rightleftharpoons {CO}_2\left(g\right)$ is:

• A. $RT$
• B. $\frac{1}{\sqrt{RT}}$
• C. $\sqrt{RT}$
• D. $1$

Answer 1

The correct option is B $\frac{1}{\sqrt{RT}}$

$K_p/K_c$ for the reaction, $CO\left(g\right)+\frac{1}{2}{O}_2\left(g\right)\rightleftharpoons {CO}_2\left(g\right)$ is $\frac{1}{\sqrt{RT}}$.

$\Delta n=1-(1+\frac{1}{2})$

$\Delta n=-\frac{1}{2}$

$K_p/K_c=(RT{)}^{\Delta n}$

$K_p/K_c=(RT{)}^{-\frac{1}{2}}$

Option B is the correct answer.
