Dissociation energy

Postby Austin Clack » Wed Nov 07, 2018 4:01 pm

We discussed in lecture that dissociation energy is always measured to be positive I was wondering if there are any set of circumstances that would allow this value to become negative?

I don’t think a negative value is possible. A negative number would mean that energy is released when a bond is being broken, but energy is only released when bonds are formed.

Because it always takes energy to break bonds, bond dissociation energy is always positive.

so there would never be a negative answer?
