Re: Negative Ea

Activation energy cannot be negative because it is the minimum amount of energy that a reaction requires to undergo a specific reaction, making it positive. So if the activation energy were to be negative, then that would mean there is a release of energy.

Re: Negative Ea

The activation energy cannot be negative, but it can be decreased with the addition of a catalyst as it provides an alternative pathway between reactants and products.
