###### Problem Details

A solution is formed when the solute uniformly disperses throughout (or dissolves in) the solvent. The process can be described by three steps:

1. separation of solvent-solvent particles (AKA expanding the solvent),

2.separation of solute-solute particles (AKA expanding the solute), and

3. formation of solute-solvent interactions.

Classify the steps involved in the formation of a solution as being endothermic or exothermic.

a. Step 1 is exothermic, Step 2 is exothermic, Step 3 is endothermic

b. Step 1 is endothermic, Step 2 is endothermic, Step 3 is exothermic

c. Step 1 is endothermic, Step 2 is exothermic, Step 3 is exothermic

d. Step 1 is exothermic, Step 2 is endothermic, Step 3 is exothermic
