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?

Explanation:

It is often convenient to treat the heat of reaction as if it were a reactant or a product. For this reaction, we could write

2CO + O₂ ⟶ 2CO₂ + 135.28 kcal

We could consider the “kcal” as an element with 135.28 as the coefficient in the equation.

The molar ratio would be 135.28 kcal:2 mol CO . Then,

i think its 5049.

i hope this !
