WebIt is convenient to define a new function H, the enthalpy of the system: H = U+PV. (5) A change in enthalpy takes account of the heat absorbed at constant pressure, and the work done by the P∆V term. The specific heat ca-pacity measured at constant pressure is therefore given by: CP = µ ∂H ∂T ¶ P. (6) Webchange in enthalpy during a reaction is mainly due to change in internal energy of the system which includes potential,rotational,translational KE as well. But in this case we are considering only the potential energy.So …
