(1) an exothermic reaction.
(2) an endothermic reaction.
(3) a reaction that is neither endothermic nor exo-
thermic.
(4) a reaction in which a catalyst is used.​

Answer 1

Answer:

So if the sum of the enthalpies of the reactants is greater than the products, the reaction will be exothermic. If the products side has a larger enthalpy, the reaction is endothermic. You may wonder why endothermic reactions, which soak up energy or enthalpy from the environment, even happen.

Answer 2

Answer:

Answer is option 2 an endothermic reaction because reactants absorbs heat here.
