please answer the above question (all parts )

True/False (Justification for each answer is expected) a. Since entropy never decreases, the earth must increase in entropy. b. Total entropy can increase but does not necessarily increase in a reversible process. c. Entropy can be thought of as an efficiency cap or limit. d. Entropy can be thought of as a tendency towards disorder. e. Adding a degree of freedom to a system tends to lower its entropy. f. Some processes are inherently irreversible so there is no reversible path to the final conditions. g. Two processes that have the same final and initial conditions can have any amount of total heat and work. h. A reversible process contains non-equilibrium states in between equilibrium ones. i. All exothermic reactions are spontaneous
