In the reaction, A2(g) + 4 B2(g) 2AB4(g) + heat the formation of AB4will be favoured at
A.Low temperature, high pressure✓ Correct
B.High temperature, low pressure
C.Low temperature, low pressure
D.High temperature, high pressure
Explanation
As in 2 2 4 A 4B 2AB , no. of moles of reactant are more than product, so reaction can be favored by increasing pressure as it shifts equilibrium towards less no. of moles side also H 0 , so reaction is exothermic, then according to Le-Chatelier’s principle, reaction can be favored at low temperature.
