Carbon monoxide reacts with oxygen to form carbon dioxide by the following reaction: 2 CO(g) + O2(g) → 2 CO2(g)∆H for this reaction is −135.28 kcal. How much heat would be released if 12.0 moles of carbon monoxide reacted with sufficient oxygen to produce carbon dioxide? Use only the information provided in this question. 1. 270.56 kcal 2. 1623.36 kcal 3. 811.68 kcal 4. 405.84 kcal 5. 541.12 kcal 6. 135.28 kcal

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,

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 =

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