dissociation energy

[Elyssa Smith 4B]

Why is disassociation energy always positive?

[Nathan Nakaguchi 1G]

I'm not 100% on this but I believe Dissociation energy is always positive because breaking a bond will always require an input of energy, if it were to release energy dissociation energy would be negative but that can't happen because breaking a bond is going from a lower potential energy to a higher potential energy.

Dissociation energy is always positive because then dissociation energy is the energy required to break a bond and breaking a bond will always require an input of energy while forming bonds release energy.

[Frederick Keith_4C]

Dissociation energy is defined as the energy needed to break every chemical bond in a molecule and completely separate all of its atoms. This bond-breaking process is endothermic as it requires an input of energy to do so, and will always result in a positive number.

[Ashley Kim 3F]

Dissociation energy is always positive because you are inputting energy into the system, not taking it out.

[Bradley Whitworth 4B]

Breaking a bond always requires some energy so dissociation energy is always positive.

[pauline young 1L]

since you are trying to break bonds, energy is always required (its always going in) and therefore it is always going to be positive.

[kristi le 2F]

Breaking a bond requires energy since bound atoms have lower energy than free atoms. Therefore, forming a bond releases energy.
