Calculate the heat required when 2.50 mol of A reacts with excess B and A₂B according to the reaction:
2A + B + A₂B $\rarr$ 2AB + A₂
Given:
$\begin{array}{ll}2 \mathrm{~A}+\mathrm{B} \rightarrow \mathrm{~A}_{2} \mathrm{~B} & \Delta \mathrm{H}^{\circ}=-25.0 \mathrm{~kJ} / \mathrm{mol} \\2 \mathrm{~A}_{2} \mathrm{~B} \rightarrow 2 \mathrm{AB}+\mathrm{A}_{2} & \Delta \mathrm{H}^{\circ}=35.0 \mathrm{~kJ} / \mathrm{mol}\end{array}$
