Question

Analyze the figure shown of a salt (sodium chloride) dissociating in a solvent
(water).
Identify two factors that affect the change in entropy that occurs during the
formation of the solution. State whether each factor causes an increase or a
decrease in entropy.

Answer 1

1. Temperature: Increase in temperature causes an increase in entropy.
2. Concentration of the solution: Increase in concentration of the solution causes a decrease in entropy.
