Which of the following statement(s) is/are false? (A) All adiabatic processes are isoentropic (or isentropic) process (B) The heat of vaporization of water at 100°C is 40.6 kJ/mole. When 9g of water vapour condenses to liquid at 100°C of 1 atm, then ΔS_system = 54.42 J/K (C) When (ΔG_system)_T,P < 0; the reaction must be exothermic (D) dG = Vdp - S dT is applicable for closed system, both PV and non-PV work
