951 mol of N2 gas is in a constant volume 235.6 L turbine at 25 °C. If 11.36 MJ of heat energy is added the gas will heat up to 600 °C. a. calculate CP,m= ΔH/ΔT/n. b. If we Google the heat capacity we find CP,m = 29.135 J/K/mol at room temperature. The result from pt. a is slightly higher! Can you explain the discrepancy?

Question
Let’s say 951 mol of N2 gas is in a constant volume 235.6 L turbine at 25 °C. If 11.36 MJ of heat energy is added the gas will heat up to 600 °C.
a. calculate CP,m= ΔH/ΔT/n.
b. If we Google the heat capacity we find CP,m = 29.135 J/K/mol at room temperature. The result from pt. a is slightly higher! Can you explain the discrepancy?
