Dissociation of phosphorus pentachloride is favoured by –

Options

  1. AHigh temperature and high pressure
  2. BHigh temperature and low pressure
  3. CLow temperature and low pressure
  4. DLow temperature and high pressure

Correct answer

B. High temperature and low pressure

Step-by-step solution

P C l 5 → Δ P C l 3 + C l 2 , Number of molecules in products is higher than that of reactant thus low pressure condition favours reaction in forward direction.
