Question

What is the second law of thermodynamics? For any process, there are four possible sign combinations for ᅀSsys and ᅀSsurr. Which sign combination(s) always give a spontaneous process? Which sign combination(s) always give a non-spontaneous process? Which sign combination(s) may or may not give a spontaneous process?

Solution Preview

The second law of thermodynamics deals with the direction of a natural process. It states that the total entropy of an isolated system can never decrease over time. For spontaneous processes the entropy increases with time and the process is irreversible. The change in entropy for a spontaneous process is always positive. Depending upon the sign combinations the process can be classified as a spontaneous or a non spontaneous process.
