Question 6

For the industrial gas-phase equilibrium shown below, which combination of temperature and pressure would result in the greatest equilibrium yield of the products?

A2(g)+B2(g)⇌2AB(g)+B(g)ΔH=+83 kJ mol−1 \text{A}_2(g) + \text{B}_2(g) \rightleftharpoons 2\text{AB}(g) + \text{B}(g) \quad \Delta H = +83\text{ kJ mol}^{-1} A2​(g)+B2​(g)⇌2AB(g)+B(g)ΔH=+83 kJ mol−1
