Q. For the reaction $CO(g) + 0.5O_{2}(g) \rightarrow CO_{2}(g)\ \ \frac{K_{p}}{K_{c}}$ is equal to
A) $\sqrt{RT}$
B) $\frac{1}{\sqrt{RT}}$
C) 1
D) $RT^{2}$
Explanation
(b)
$CO(g) + 0.5O_{2}(g) \rightarrow CO_{2}(g)$
$\mathrm{\Delta}n_{g} = n_{p} - n_{r} = 1 - 1.5 = - 0.5$
$K_{p} = K_{c}(RT)^{\mathrm{\Delta}n} = K_{c}(RT)^{- 0.5}$
$\frac{K_{p}}{K_{c}} = \frac{1}{\sqrt{RT}}$
