Answer:
2CO + O2 =====> 2CO2 ΔH = -566 KJ
Step-by-step explanation:
A thermochemical equation is a chemical equation that includes the enthalpy change of the reaction (Lumen Learning).
In a thermochemical equation, we can easily see the heat of reaction written after the symbols of reactants and products. It tells us whether heat was evolved or gained in the chemical process. When heat is gained ΔH = positive. When heat is evolved, ΔH = negative.
The thermochemical equation for the reaction of CO and O2 is shown below;
2CO(g) + O2(g) =====> 2CO2 (g) ΔH = -566 KJ
