Question
Which of the following statement(s) is/are false ?
Options
A.All adiabatic processes are isoentropic (or isentropic) processes
B.When (ᐃGsystem) T,P < 0; the reaction must be exothermic
C.dG = VdP - SdT is applicable for closed system, both PV and non-PV work
D.the heat of vaporisation of water at 100oC is 40.6 kJ/mol. When 9 gm of water vapour condenses to liquid at 100oC of 1 atm, then ᐃSsystem = 54.42 J/K
Solution
(A) Reversible adiabatic process is isoentropic
(B) Reaction is spontaneous, need not be exothermic.
(C) Only when PV work is innvolved
(D) ᐃSsystem =
= - 54.42 J/K
