Answer: 1. Low temperature and high pressure

Apply Le Chatelier's principle to \(\mathrm{A_2+B_2\rightleftharpoons X_2}\), which is exothermic and reduces the number of gas moles from 2 to 1.

Exothermic, so low temperature favours the forward reaction. Fewer moles of gas on the right, so high pressure favours the product. Answer: low temperature and high pressure.
