The diagram shows that the potential energy of the products is lower
than the potential energy of the reactants. Which type of reaction is
shown?
(Once it hits the top of the hill it says activation energy
Once it hits the bottom to the word products it says heat of reaction)
A: this is an exothermic reaction because the reactants have less energy than the products
B: this is an endothermic reaction because the reactants have more energy than the products
C: this is an endothermic reaction because the reactants have less energy than the products
D: this is an exothermic reaction because the reactants have more energy than the products
