Exothermic Reaction DEFINITION A chemical reaction in which heat is given out from (System to surrounding) is called Exothermic reaction. ENDOTHERMIC REACTION THE CHEMICAL REACTION IN WHICH HEAT IS ABSORBED FROM (SURROUNDING TO SYSTEM) ACTIVATION ENERGY Minimum amount of energy require to start a chemical reaction is called activation energy. RADIO ACTIVE ISOTOPE (URINIUM 235 ) As A Source Of Energy
