Activation energy is always a positive quantity.It never have a negative energy.

Yes sometime it is negative in case of backward reaction

There are instances where the activation energy can be negative. There are reactions where the rate of the reaction decreases with increasing temperatures. This happens because the when you increase the temperature, it can sometimes reduce the probability of molecules colliding as the increased momentum carries the molecules away from the potential “collision zone.” So when you fit the rate constant into an Arrhenius expression, it results in a negative activation energy. But these reactions are generally the ones without barriers. So there’s no activation energy per se.
