The heat capacity at constant pressure. (C_p) is the partial of the enthalpy with respect to temperature at constant pressure Therefore, the integral of C_p is equal to the enthalpy change for the interval of the integration, i.e., delta h = h(T_2) - h(T_1) = integral^T_2_T_1 C_p dT. Determine the enthalpy change for CO_2, between 1500 degree C and 100 degree C using (a) the trapezoidal method and (b)Simpson's rule and the following heat capacity data for CO_2 where the heat capacity is given in J g/mol- degree C
