Question

$\frac{K_{p}}{K_{c}}$ for following reaction will be $\quad\quad$ $CO_{\left(g\right)}+\frac{1}{2}O_{2\left(g\right)}\rightarrow CO_{2\left(g\right)}$

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

Answer 1

Answer: (C)

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

Answer 2

$\Delta_{n_g}=n_{p}-n_{r}=1-\frac{3}{2}$ $\Delta _{n_g}=\frac{-1}{2}.$Hence$K_{p} = K_{c}\left(RT\right)^{-1/2}$ $\frac{K_{p}}{K_{c}}=\frac{1}{\left(RT\right)^{1/2}}=\frac{1}{\sqrt{RT}}$
