One mole of methanol, when burnt in oxygen gives out 723 kJ $m o l^{- 1}$ heat. If one mole of oxygen is used, what will be the amount of heat evolved?

Options:

Answer:

Solution:

${CH}_{3} OH + \frac{3}{2} O_{2} \overset{}{\to} {CO}_{2} + 2 H_{2} O$

$ΔH= \frac{2}{3} \times 723 = 2 \times 241 = 482 kJ$
