The enthalpy of the reaction can be obtained from the enthalpies of formation as -16.2 kJ/mol.
<h3>What is the enthalpy of reaction?</h3>
We know that any time that there is a chemical reaction, there is an interaction that place between the reactants and the products and as such we are going to get new substances and these are the substances that I have referred to here as the products of the reaction.
In this case, we are asked to obtain the enthalpy change of the reaction. This tells us the heat that could have been absorbed or evolved in the reaction. We have to at this point know that the enthalpy change of the reaction gotten from;
Sum of enthalpy of the products - Sum of enthalpy of the reactants
ΔH = [(-484.5)] - [(-393.5) + (-74.8)]
ΔH = (-484.5) + 468.3
ΔH = -16.2 kJ/mol
