Answer 1

Answer:

In an exothermic reaction, ΔH is less than zero because the energy of the reactants is greater than the energy of the products. Energy is released in the reaction.

In an endothermic reaction, ΔH is greater than zero because the energy of the reactants is less than the energy of the products.

Answer 2

Explanation:

The heat of reaction (ESBQQ)

In an exothermic reaction, ΔH is less than zero because the energy of the reactants is greater than the energy of the products. Energy is released in the reaction. ...

In an endothermic reaction, ΔH is greater than zero because the energy of the reactants is less than the energy of the products.
