The value of ΔH for the reaction

X2 (g) + 4Y2 (g) ⇌ 2XY4 (g) is less than zero. Formation of XY4 (g) will be favoured at

  • Low pressure and low temperature

  • high temperature and low pressure

  • high pressure and low temperature

  • high temperature and high pressure

Answer

C.

high pressure and low temperature

X2 (g) + 4Y2 (g) ⇌ 2XY4 (g);


ΔH < 0 and Δn < 0
Therefore, the forward reaction is favoured at high pressure and low temperature. (According to Le- Chatelier's principle)
