Question

For the reaction $CO\left(g\right)+C{l}_2\left(g\right)\rightleftharpoons COC{l}_2\left(g\right)$ the value of $\frac{K_p}{K_c}$ is equal to :

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

Answer 1

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

$CO\left(g\right)+C{l}_2\rightleftharpoons COC{l}_2\left(g\right)$
In given equation
$\Delta n=1-(1+1)=-1$
Relation between $K_p$ and $K_c$ is
$K_p=K_c(RT{)}^{\Delta n}$
$\frac{K_p}{K_c}=(RT{)}^{-1}$
$=\frac{1}{\left(RT\right)}$
$=\frac{1}{RT}$
