    @Supernaturallvr24 in an endothermic reaction energy must be absorbed from the surroundings to get it going. in an exothermic reaction heat is released from the reaction. look at these diagrams. for an endothermic reaction notice that if we subtract the difference in energy between products - reactants we get a positive value? it's an endothermic reaction. for an exothermic reaction the energy difference between products and reactants is negative, that means that heat is lost and you can see this because the products are at a lower energy than the reactants and are more stable. |dw:1443412676933:dw|
