The quantity that will always have a negative value is:
**the change in the energy in a system during an exothermic reaction.**
In an exothermic reaction, energy is released to the surroundings, leading to a decrease in the energy of the system. Consequently, the change in energy (ΔE) for an exothermic process is negative.
**the change in the energy in a system during an exothermic reaction.**
In an exothermic reaction, energy is released to the surroundings, leading to a decrease in the energy of the system. Consequently, the change in energy (ΔE) for an exothermic process is negative.
