A Thermochemical Equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH. In variable form, a thermochemical equation would look like this:
A + B → C. ΔH = (±) #
The thermochemical reaction is of two types:
Endothermic Reaction Those thermochemical reactions in which heat is absorbed. Change in enthalpy for this reaction is positive.
Exothermic Reaction Exothermic reactions are the reaction in which the heat or the energy is evolved during the reaction.
