हिन्दीWhich one of the following conditions will favour maximum formation of the product in the reaction? \( \mathrm{A}_{2(\mathrm{g})}+\mathrm{B}_{2(\mathrm{g})} \rightleftharpoons \mathrm{X}_{2(\mathrm{g})} ; \Delta_{r} \mathrm{H}=-x \mathrm{kJ} \)
Correct answer · Option A
Low temperature and high pressure
Explanation
Since the reaction is exothermic (\( \Delta H < 0 \)) and involves decrease in moles of gas (\( \Delta n = 1 - 2 = -1 \)), low temperature and high pressure favor the forward reaction according to Le Chatelier's principle.
