Question:

All of the following processes lead to an increase in entropy EXCEPT?

a. decreasing the volume of a gas.

b. melting a solid.

c. chemical reactions that increase the number of moles of gas.

d. forming mixtures from pure substances.

e. increasing the temperature of a gas.

Microstates:

A microstate is a way in which the energy of a system can be arranged. The more microstates that are available for the system, the more disordered the system will be and an increase in entropy will be observed. Entropy is noted with the symbol S and is a measure of the disorder of a system.
