does this graph show an endothermic of exothermic reaction?
(WILL GIVE BRAINLIEST)
1. endothermic, because the products are at a lower energy state in the reactants
2. endothermic, because it takes a lot of energy to cause the reaction to occur
3. exothermic, because the products are at a lower energy state in the reactants
4. exothermic, because it takes a lot of energy to cause the reaction to occur
