Solution

The correct option is B $2 S O_{2} (g) + O_{2} (g) ⇋ 2 S O_{3} (g)$
We know,
$K_{p} = K_{C} (R T)^{△ n_{g}}$
So, $l o g K_{p} = l o g K_{C} (R T)^{△ n_{g}}$
$\Rightarrow l o g K_{p} - l o g K_{C} = △ n_{g} l o g (R T)$
$log \frac{K_{P}}{K_{C}} = △ n_{g} log R T$

So, according to the question $△ n_{g} = - 1$

Hence, for the reaction
$2 S O_{2} + O_{2} ⇋ 2 S O_{3} △ n_{g} = n_{p} - n_{R} = 2 - 3 = - 1$
