From Maxwell Boltzmann distribution it can be deduced that the fraction of collisions with more energy than the activation energy is $e^{\frac{-E_a}{k_BT}}$ .

but from my understandint minimum energy needed = threshold energy so, in place of Ea it should be thershold i,.e. Ea + energy of molecules(KE) any comments? and in NCERT there is a blunder where its written that rate = PZe^-E/RT is written but that is the rate constant ..
