Carbon monoxide reacts with oxygen to form carbon dioxide by the following reaction: 2 CO(g) + O2(g) → 2 CO2(g)∆H for this react
MrMuchimi

Answer : The amount of heat released would be, (3) 811.68 kcal

Explanation :  Given,

Moles of carbon monoxide = 12.0 mole

Enthalpy change = -135.28 kcal

The given balanced chemical reaction is,

2CO(g)+O_2(g)\rightarrow 2CO_2(g)

From the balanced chemical reaction we conclude that,

As, 2 moles of carbon monoxide react to release heat = 135.28 kcal

So, 12.0 moles of carbon monoxide react to release heat = \frac{12.0}{2}\times 135.28kcal=811.68kcal

Thus, the amount of heat released would be, 811.68 kcal
