can a reaction have zero activation energy? nd why?

no activation energy of a reaction cannot be zero...because in that case every collison among reactant molecules will be effective collison...however this is not possible...so activation energy of reactants cannot be zero

For explosive reaction ,the value of Ea is zero

Spontaneous reactions have 0 Ea

Negative activation energy. In some cases, rates o freaction decrease with increasing temperature. When following an approximately exponential relationship so the rate constant can still be fit to an Arrhenius expression, this results in a negative value of Ea.

Activation Energy in general case can't be 0 as it implies there is no energy difference between reactant and activated complex. So reaction will take place always
