The value of ΔH for the reaction X 2 (g) + 4Y 2 (g) ⇌ 2XY 4 (g) is less than zero. ​Formation of XY 4 (g) will be favoured at

Options

  1. Ahigh temperature and high pressure
  2. Blow pressure and low temperature
  3. Chigh temperature and low pressure
  4. Dhigh pressure and low temperature

Correct answer

D. high pressure and low temperature

Step-by-step solution

X 2 (g) + 4Y 2 (g) ⇌ 2XY 4 (g) Δn g = –ve and ΔH = –ve (exothermic) According to Le-Chatelier's principle: The reaction is favoured in forward direction at low temperature and high pressure.
