The degree of dissociation of
The degree of dissociation of \( \boldsymbol{P C l}_{5} \)
- A. increases with increasing pressure
- B. decreases with increasing pressure
- C. no effect on change in pressure
- D. decreases with decreasing pressure
Step-by-step solution
The dissociation of PCl5 is PCl5(g) ⇌ PCl3(g) + Cl2(g), which increases the number of moles from 1 to 2. According to Le Chatelier's principle, increasing pressure shifts the equilibrium toward the side with fewer moles (reactants), thus decreasing the degree of dissociation.
