Ideal gas ethylene undergoes a reversible adiabatic compression by which its temperature increases from T1 = 300 K to T2 = 450 K. The molar entropy in the initial state is given as s1 = 100 J K–1 mol–1, and here, for ethylene, cp = ?T + c0 with ? = 0.1 J K–2 mol–1 and c0 = 13.1 J K–1 mol–1. Determine the change of the molar entropy s2 – s1 and the change of the chemical potential ?2 – ?1 for the fluid during this process.
