Question

8) According to the second law of thermodynamics, a spontaneous reaction must result in no change in free energy for the reaction. b. the enthalpy of the universe increasing. s the entropy of the universe decreasing. d, the temperature of the surrounding increasing e, the entropy of the universe increasing. 19) In order to get the most efficient work out of a thermochemical process, what needs to be done? a. The process must take place at high temperature. b. The process must be endothermic. c. The process must be exothermic d. The process must be done reversibily e. The process must cause an increase in entropy for the system

Explanation / Answer

According to second law of thermodynamic

e) The entropy of the universe is increasing.

19)

d) the process must be done reversibly.

Inreversible process we can get continuous work without losing heat.but in practical this can't be possible
