question

Formation of a solution can often be visualized as a three-step process. Step 1. Solvent molecules are separated from each other to make space for the solute. Step 2. Solute molecules are separated so they fit into spaces in the solvent. Step 3. Separated solute and solvent are brought together, filling in the spaces. Which of the following statements about the energy involved in the above is correct?

choices

  1. Steps 1 and 2 are exothermic, and step 3 is endothermic.
  2. Steps 1 and 2 are endothermic, and step 3 is exothermic.
  3. All three steps are exothermic.
  4. All three steps are endothermic.
