The energy which is needed for an endothermic reaction comes from the product/reactant solution and from the environment when no solution is involved.

The reactions which absorb energy from the surroundings to form products are known as Endothermic reactions.

A cooling effect is produced during these reactions because the temperature of the surroundings reduces. The energy that is required for the bond breakage and to proceed with the reaction is taken from the surrounding or from the product reactant solution.

The enthalpy change of this endothermic reaction is positive. Dissolution of ammonia chloride into water is an example of endothermic reactions.
