1.	Which of the following statement(s) is/are false?A. All adiabatic process are isoentropic (or isentropic) processesB. When `(DeltaG_("system"))_(T,P)lt0,` the reaction must be exothermicC. dG=VdP-SdT is applicable for closed system, both PV and non-PV workD. The heat of vaporisation of water at `100^(@)C` is 40.6 kJ/mol. When 9 gm of water vapour condenses to liquid at `100^(@)C` and 1 atm, then `DeltaS_("system")` = 54.42 J/K
Answer» Correct Answer - A::B::C::D (a) Reversible adiabatic process is iso-entropic process (b) When `(DeltaG_("system"))_(T,P)lt0` then process may be endothermic / exothermic (c )`dG=VdP -SdT`, only PV work consider (d) `DeltaS=-(9)/(18)xx(40.6 xx 1000)/(373)=-54.42`
