Solution Formation and Solubility Quiz

What is the first step in the three-step process of solution formation?

• Forming new intermolecular forces

• Breaking apart solvent molecules

• Cooling the solution

• Mixing solute and solvent

Which of the following is true about delta H in a spontaneous solution process?

• Delta H must always be positive

• Delta H is irrelevant

• Delta H should be as negative as possible

What is the role of entropy in the spontaneity of a solution process?

• An increase in entropy favors spontaneity

• Entropy must be zero for spontaneity

• Entropy has no effect on spontaneity
