The change in the internal energy of a substance

The enthalpy change for chemical reaction is denoted as DeltaH^(Theta) and DeltaH^(Theta) = H_(P)^(Theta) - H_(R)^(Theta) . The relation between enthalpy and internal energy is expressed by equation: DeltaH = DeltaU +DeltanRT where DeltaU = change in internal energy Deltan = change in number of moles, R = gas constant. Enthalpy of the system is given as
