When the products of a reaction have more energy than the reactants:

The reaction is exothermic.

The reaction is endothermic.

The reactants gave up energy.

The ΔH is positive.

Verified Answer :

when the products of a reaction have more energy than the reactants, the reaction is endothermic.  Since the products have more energy than the reactants, we know that the reactants had to get energy from the surroundings which means the ΔH is positive meaning the reaction is endothermic.

I hope this helps.  Let me know in the comments if anything is unclear.

In an endothermic reaction, the reaction mixture absorbs heat from the surroundings. Therefore, the products will have higher energy than the reactants and ΔH will be positive. Hence, options B and D are correct.

What is an endothermic reaction?

Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.

When enthalpy is positive and delta H is greater than zero, this means that a system absorbed heat. This is called an endothermic reaction.

In an endothermic reaction, the reaction mixture absorbs heat from the surroundings.

Therefore, the products will have higher energy than the reactants and ΔH will be positive.

Hence, options B and D are correct.
