💡 Solution & Explanation

(A) Spontaneity requires G  to be negative. Here H  is positive but nothing can be said about S , so the process may or may not be spontaneous. Hence, option (A) is incorrect. (B) Since, S 0   so G H   but H U P V    , so this process can be spontaneous if V is negative or zero or even small positive. But nothing is mentioned about V , so the process may or may not be spontaneous. So, (B) is incorrect. (C) For a reversible adiabatic process, Syst surr S S 0    and for an irreversible adiabatic process, syst surr S 0 and S 0     So, (C) is incorrect.
