Indicate whether each statement is true or false.

a. When a solution is made, the enthalpy of mixing is always a positive number.
b. An increase in entropy favors mixing.
c. A solute will dissolve in a solvent if solute-solute interactions are stronger than solute-solvent interactions.

Sagot :

Answer: a. False.

b. True

c. False

Explanation:

a. When a solution is made, the enthalpy of mixing is always a positive number.

This is false. It should be noted that the nature of reaction determine the enthalpy which can either be positive or can be negative.

b. An increase in entropy favors mixing.

This is true because when molecules get randomly distributed, they mix with one another. Therefore, an increase in entropy favors mixing.

c. A solute will dissolve in a solvent if solute-solute interactions are stronger than solute-solvent interactions.

This is false. This is because the solute-solute interactions have to be weaker and not stronger.
