Answered by admin @
Answer:
Exothermic chemical reaction
Endothermic chemical reaction
An Exothermic chemical reaction releases energy, whereas an Endothermic chemical reaction requires an input of energy.
An Exothermic chemical reaction involves the release of heat(thermal energy) in a system to the surroundings. The enthalpy(heat) change which is ΔH decreases in this type of reaction
An Endothermic chemical reaction involves the absorption or input of heat in the form of thermal energy by the system from the surroundings. The enthalpy(heat) change which is ΔH increases in this type of reaction.
