Question

The ratio of $K_p$ to $K_c$ for the equilibrium $CO\left(g\right)+\frac{1}{2}{O}_2\left(g\right)\rightleftharpoons C{O}_2\left(g\right)$ is

• A. 1
• B. RT
• C. $\frac{1}{\sqrt{RT}}$
• D. $(RT{)}^{\frac{1}{2}}$

Answer 1

The correct option is C

$\frac{1}{\sqrt{RT}}$

$K_P=K_C(RT{)}^{△n};△n=1-(1+\frac{1}{2})=-\frac{1}{2}$

$\frac{K_P}{K_C}=(RT{)}^{-\frac{1}{2}}=\frac{1}{\sqrt{\left(RT\right)}}$
