Question

For the reaction, $C{O}_{\left(g\right)}+C{l}_{2\left(g\right)}\leftrightharpoons COC{l}_{2\left(g\right)}$, the value of $K_p/K_c$ is equal to:

• A. $1.0$
• B. $RT$
• C. $\sqrt{RT}$
• D. $\frac{1}{RT}$

Answer 1

The correct option is D $\frac{1}{RT}$

Answer:-

$\Delta n=n_P-n_R$

Here, $\Delta n$ = Change in number of moles

$\Delta n=1-2=-1$

As we know that,

$K_P=K_C{\left(RT\right)}^{\Delta n}$

$\Rightarrow K_P=K_C{\left(RT\right)}^{-1}$

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