Question

The degree of dissociation of PCl₅(α) obeying the equilibrium,

PCl₅(g) ⇌PCl₃(g) + Cl₂(g) , is approximately related to the pressure at equilibrium by:

• A. $\alpha$ $\propto$ p
• B. $\alpha$ $\propto$ $\frac{1}{\sqrt{p}}$
• C. $\alpha$ $\propto$ $\frac{1}{p^2}$
• D. $\alpha$ $\propto$ $\frac{1}{p^4}$

Answer 1

The correct option is B $\alpha$ $\propto$ $\frac{1}{\sqrt{p}}$
