Question on: JAMB Chemistry - 2023
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
Ask EduPadi AI for a detailed answer
Correct Option: A
The highest entropy change is generally associated with the transition from a more ordered state to a more disordered state.
In this case, the transition from a liquid to a gas (Option A: Liquid → Gas) involves an increase in disorder because gas particles are more randomly distributed and have greater freedom of movement compared to liquid particles.
Therefore, the process of a substance changing from a liquid to a gas typically results in the highest entropy change among the given options.
