The Arrhenius equation is given by 
k=Ae^{-E_{a}/RT}.................................(i)
given equation,
k = (4.5 × 1011s^{-1}) e^{-28000K/T}............................(ii)

by comparing equation (i) & (ii) we get,

A= 4.51011 per sec
E_{a}/RT =28000/T
Activation energy = 28000 \times (R = 8.314)
                             = 232.792 KJ/mol
