Question 1 of 5

A gas mixture analysing 30%(mole) CO, 30%(mole) $\mathrm{H}_2$ and $40 \%($ mole $) \mathrm{N}_2$ is burned in air. The following heats of reaction data are available:

$\mathrm{CO}+\frac{1}{2} \mathrm{O}_2 \rightarrow \mathrm{CO}_2 \Delta H_r^{\circ}=-282.91 \mathrm{KJ} / \mathrm{mol}$

$\mathrm{H}_2+\frac{1}{2} \mathrm{O}_2 \rightarrow \mathrm{H}_2 \mathrm{O} \Delta \mathrm{H}_r^{\circ}=-241.83 \mathrm{KJ} / \mathrm{mol}$

If only 80% of the CO and 70% of the $\mathrm{H}_2$ react, how much heat in kJ is liberated on the combustion of 100 mole of the mixture?
