hen CO(g) reacts with O2(g) to form CO2(g) , 283 kJ of energy are evolved for each mole of CO(g) that reacts. Write a balanced t
hermochemical equation for the reaction with an energy term in kJ as part of the equation. Note that the answer box for the energy term is case sensitive. Use the SMALLEST INTEGER coefficients possible and put the energy term (including the units) in the last box on the appropriate side of the equation. If a box is not needed, leave it blank.
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;
