Solution

The correct option is D 1
$\begin{matrix} P C l_{5} & ⇌ & P C l_{3} & + & C l_{2} A t e q u i l i b r i u m & 2 & 2 & 2 \end{matrix}$
$P_{C l_{5}} = \frac{2}{6} \times 3, P_{P_{C l_{3}}} = \frac{2}{6} \times 3, P_{C l_{2}} = \frac{2}{6} \times 3$
$K_{p} = \frac{p_{P C l_{3}} \times p_{C l_{2}}}{p_{P C l_{5}}} = \frac{1 \times 1}{1} = 1$
