Question
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
Solution
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)
