Which of the following reactions would be expected to have the highest entropy change?
A.
Liquid → Gas
B.
Solid → Liquid
C.
Gas → Liquid
D.
Gas → Solid
Correct answer is A
The phase change from a liquid to a gas involves an increase in entropy. In the gas phase, molecules have higher degrees of freedom and are more dispersed compared to the liquid phase, resulting in higher entropy change.
