Answer 2

The optimum conditions to obtain maximum yield in the given reaction are high temperature and low pressure.

- The given reaction is :

N₂O₄ (g) ⇄ 2NO₂ (g) ; ΔH = +ve

- Here, the no of moles of gaseous products is more than the no of moles of gaseous reactants.

- In such case, according to Le Chatelier's principle, low pressure will favour the formation of more products.

- It is given that ΔH = +ve. This means that heat is being supplied to the system, i.e., the reaction is endothermic.

- According to Le Chatelier's principle, for endothermic reaction, high temperature will favour the formation of more products.

- So optimum conditions are low pressure and high temperature.
