Answer :
Final answer:
The heat of solution for LiCl being -37.1 kJ/mol indicates it is an exothermic reaction, as evidenced by the release of energy to its surroundings during dissolution. Hence, the correct option is b) Exothermic
Explanation:
The heat of solution for LiCl is -37.1 kJ/mol, which indicates the amount of heat energy released or absorbed when a specific amount of solute dissolves in a solvent. The negative value specifies that heat is released during the process, making it an exothermic reaction. In exothermic reactions, the system releases energy to its surroundings, and this is exemplified by the dissolution of LiCl in water where the surrounding solution absorbs heat, leading to an increase in temperature.
