Which of the following curves correctly represents the process of antibiotic production by Streptomyces sp ?

Which of the following statement (s) is correct? Statement-I: The entropy of isolated system with P-V work only, is always maximized at equillibrium. Statement-2: It is possible for the entropy of closed system to decrease substantialy in an irreversible process. Statemet-3: Entropy can be crearted but not destroyed. Statement-4 DeltaS_(system) is zero for reversible process in an isolated system.

Which of the following statement(s) is /are correct: Statement (a): The entropy of isolated system with P-V work only is always maximized at equilibrium Statement (b) : It is possible for the entropy of closed system to decrease substanilly in a irreverrsible process. Statement (c): Entrophy can be created but not destrpoyed . Statment (d) : DeltaS_(system) is always zero for reversible processe in an isolated system

(A): In an isolated system the entropy increases. (R ): The process in an isolated system are adiabatic. (2006)
