Which quantity will always have a negative value?(1 point)

Question

the change in energy in a system during an exothermic reaction
the total bond energy of the products during an exothermic reaction
the total bond energy of the reactants in an endothermic reaction
the change in energy in a system during an endothermic reaction

Answer 1

The quantity that will always have a negative value is the change in energy in a system during an exothermic reaction.

In an exothermic reaction, the system releases energy to the surroundings, resulting in a decrease in the internal energy of the system, which is represented as a negative change in energy (ΔE < 0).
