Answer: energy will be transferred into the system and the reaction will become endothermic.
Explanation: When the solution of Lithium chloride is heated that means the system is solution of lithium chloride and by heating, we are providing the sufficient amount of energy to the system. Thus in other words, energy will be transferred into the system.
Moreover, the system now will represent an example of endothermic reaction as the energy is being provided to the system and the process of dissolution is basically an endothermic reaction in which the heat is being transferred to the system.
