3BA The molar heat capacity of N,(g) in the range 200 K to 400 K is given by Com/(J K'mol') = 28.58 + 3.77× 10*(T/K). Given that the standard molar entropy of N,(g) at 298 K is 191.6JK mol', calculate the value at 373 K. Repeat the calculation but this time assuming that Cm is independent of temperature and takes the value 29.13 JK'mol. Comment on the difference between the results of the two calculations. P,m
