Ans: The given reaction is :-

PCl5(g)?PCl3(g)+Cl2(g)

KC= $\frac{\left[\mathrm{P}\mathrm{C}\mathrm{l}3\right]\left[\mathrm{C}\mathrm{l}2\right]}{\left[\mathrm{P}\mathrm{C}\mathrm{l}5\right]}$

=1.2×10⁻³ ×1.2×10⁻³ 0.8×10−3 $\frac{[1.2\times 10-3\times 1.2\times 10-3\mathrm{}]}{[0.8\times 10-3\mathrm{}]}$

=1.8×10⁻³molL⁻¹
