Text Solution

Verified by Experts

The correct Answer is:
A
The connection between entropy and the spontanetiy of a reaction is expressed by the second lawof thermodynameics: The entropy of the universe increases in a spontaneous process and remains uncharged in an equilibrium process. For an isolated system, the energy remains constant `(Delta H = 0)`. This the increase in entropy in such a system is the natural direction of a spontaneous change. Another useful form of the second law is the for a spontaneous process in an isolated system, the change in entropy is positive.
