We’re being asked to determine the heat (q) released by the given reaction:

2 CO(g) + O2(g)  2 CO2(g); ΔH = –135.28 kcal

The problem states that 18.0 moles of CO react with 12.0 moles of O2. We first need to determine the limiting reactant.

Recall that the limiting reactant is the reactant that forms the less amount of product. This is because once the limiting reactant is all used up, the reaction can no longer proceed and make more products.

We need to perform a mole-to-mole comparison between each reactant and CO2.
