$K_P / K_C$ for the reaction at $\mathrm{T}(\mathrm{K})$ is $\mathrm{CO}(\mathrm{g})+\frac{1}{2} \mathrm{O}_2(\mathrm{~g}) \rightleftharpoons \mathrm{CO}_2(\mathrm{~g})$
  1. $\sqrt{R T}$
  2. 2RT
  3. RT
  4. $1 / \sqrt{\mathrm{RT}}$

Solution

$\mathrm{K}_{\mathrm{p}}=\mathrm{K}_{\mathrm{c}}(\mathrm{RT})^{\Delta \mathrm{n}}$ $[\Delta \mathrm{n}=$ Change in the no. gaseous molecules from reactant to product.] In this equation, $\Delta \mathrm{n}=\left(1-1-\frac{1}{2}\right)=-\frac{1}{2}$ $\therefore \frac{\mathrm{K}_{\mathrm{p}}}{\mathrm{K}_{\mathrm{c}}}=(\mathrm{RT})^{-1 / 2}=\frac{1}{\sqrt{\mathrm{RT}}}$
