The degree of dissociation of $PCl_{5} (α)$ obeying the equilibrium $PCl_{5} ⇌ PCl_{3} + Cl_{2}$ is related to the equilibrium pressure by

Options:

Answer:

Solution:

$∴ K_{p} = \frac{\frac{α}{1 + α} P \times \frac{α}{1 + α} P}{\frac{1 - α}{1 + α} P} = \frac{α ^{2} P}{1 - α ^{2}}$ or, $K_{p} = α^{2} P$ $∴ α = \frac{K _{p}}{P}$ when $1 - α^{2} = 1$
