Answer :
Answer:
An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur.
Explanation:
An Endothermic reaction is a chemical change in which the System absorbs thermal energy from its Surroundings resulting in the overall increase in its total internal energy level or Enthalpy. The energy absorbed is stored in the chemical bonds of the products. The term Endothermic, borrowed from the French word Endothermique, was first used by Pierre Eugene Marcellin Berthelot when carrying out his work on, Heat of a Reaction. The term itself is composed of two root Greek words; endon meaning inside and therm meaning heat.
