Thank you. 

The heat capacity at constant preassure (C,) is the partial of the enthalpy with respect
to temperature at constant preassure. Therefore, integral of C, is equal to the enthalpy
change for the interval of the integration, i.e.:
rT2
Ah = h(T2) – h(T1) = / C,dT.
T1
Determine the enthalpy change for CO2 between 900°C and 100°C. Use the following
