Covers Phase Changes And Energy Transfer.
During a process in a closed system at constant pressure with expansion work only, the enthalpy change equals the energy transferred across the boundary in the form of heat: Calculating molar enthalpy involves dividing the enthalpy change (δh) of a reaction by the number of moles (n) of the reactant. To calculate molar enthalpy (δh), use the formula δh = q / n, where q is the heat transferred and n is the number of moles of the substance undergoing the reaction.
