What can be said about the reactants in an endothermic reaction? (1 point) - They have more energy than the products because they absorb energy during the reaction.
- They have less energy than the products because they absorb energy during the reaction.
- They have less energy than the products because they release energy during the reaction.
- They have more energy than the products because they
release energy during the reaction.
