Question

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.

If anyone has full physics b semester exam helpp

Answer 1

in endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products! Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.

Answer 2

Answer: They have less energy than the products because they absorb energy during the reaction.

Explanation: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction.

An endothermic process is any process with an increase in the enthalpy H of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
