![The heat capacity at constant pressure of a gas is determined experimentally at several temperatures,
with the following results:
o 100 200 300 400 500 600
C,J(mol-°C)]| 33.5 | 35.1 | 36.7 38.4| 40.2| 42.0 43.9
T(°C)
(a) Calculate the heat (kW) required to raise 150 mol/s of the gas from 0°C to 600°C, using Simpson's
rule (Appendix A.3) to integrate the tabulated heat capacities.
(b) Use the method of least squares (Appendix A.1) to derive a linear expression for C,(T) in the
range 0°C to 600°C, and use this expression to estimate once again the heat (kW) required to
raise 150 mol/s of the gas from 0°C to 600°C. If the estimates differ, in which one would you have
