Revisiting Numerical Differentiation
The specific heat capacity at constant pressure CP of an ideal gas is
given by:
?H
CP =
(1)
?T P
The following data are provided for CO2 at several temperatures:
T = [750, 800, 900, 1000] (K)
H = [29.629, 32.179, 37.405, 42.769] (kJ/mol)
Use these data to determine the specific heat capacity for each of the
temperatures.

In-class Activity
Use the Lagrange interpolation polynomials of the second order to
calculate CP = CP (T ) on the first three data points, and on the second
three data points. Plot the resulting heat capacity along with the one
calculated by forward finite difference.
