Question

Does the reaction represented by this energy diagram release or absorb heat and why?A.) Release because the products have less energy than the reactants.B.) Absorb because the products have more energy than the reactants.C.) Absorb because energy must be added to reach the activated complex.D.) Release because the reactants have more energy than the products.

Answer 1

B.) Absorb because the products have more energy than the reactants.

Step-by-step explanation:

In the energy diagram we can see that (1) is the energy of the reactants and (4) is the energy of the products.

When the energy of the products is higher than the energy of the reactants, the reaction is endothermic, that means that the reaction absorbs energy.
