The molar heat capacity of N2(g) in the range 200K to 400K is given by Cpm (J/Kmol)= 28.58+3.77*10^-3 (T/K). Given that the standard molar entropy of N2(g) at 298K is 191.6 J/Kmol, change in enthalpy (H), and change of entropy of the system (Ssys) when the temperature is raised from 25C to 100C under a) constant pressure and b) constant volume.
