it's a), b), c) d) e) please solve all of them

it's thermodynamics of materials by David R. gaskell use the same way in this book

Q) answers the following questions a) what is criteria fo spontaneity of a chemical reaction under constant T and V b) sketch schematic diagrams of Carnot cycle in a)P-V , (b)T-S, c) T-V c) for the freezing of water supercooled to 2C indicate whether each of following is greater than equal to or less than zero; and (indicate the reason for each) Delta S(system) Delta S(sur) Delta S(tot) d) indicate the whether each of following statements is true and false (and why) i. (Delta)S(system) is always greater than zero ii. Q is not state function but Q(rev) is state function iii. In reversible process delta S(system) is =0 iv. For one cycle of refrigerator delta S( system) =0 e) For each of the following processes, indicate and briefly explain whether (delta)S is less than, equal to, or greater than zero, or whether there is insufficient information to decide: (Note that (delta)S refers to the system) i. Melting of ice in room at 25C ii. reversible melting of ice at 0C iii. reversible adiabatic expansion of ideal gas iv. reversible isothermal expansion of ideal gas ivv. irreversible isothermal expansion of ideal gas ivvv. crystallization of water
