Expert Answer

Step 1

The reaction is exothermic reaction when the heat is liberated in the reaction and the endothermic reactions are those reactions when the heat is required in the reaction.

 

The heat of reaction is possible because of the interactions between the solute or solvent.

 

  1. The solute molecules will be dissolved easily in the solvent when the solute-solute or solvent-solvent or both the interactions are weak. Thus, a lot of heat is produced and this reaction is highly exothermic.

 

  1. The solubility of the particles will be high when the solute-solvent interactions are strong and heat is liberated in the reaction. Such reactions are exothermic reactions.

 

  1. When the solute-solute or solvent-solvent or both the interactions are strong, then the energy is required to break the intermolecular forces between them and such reactions are endothermic reactions.

 

  1. When there is a weak interaction between solute and solvent, then the energy is required making it an endothermic reaction.
Step 2

Solution I has strong solute-solute and solvent-solvent interaction. Thus, it is endothermic.

Solution II has weak solute-solute and solvent-solvent interaction and strong solute-solvent interaction m...
