Given k=k1*(k2)1/2/k3
Taking log both the side
lnk=lnk1+lnk2(1/2)-lnk3
We know that k=Ae-Ea/RT;lnk=lnA-Ea/RT
let every step have same arrhenius constant(i.e.A) and Ea1,Ea2 and Ea3 are the corresponding activation energy for 1st,2nd and the third step respectively.
So, k=lnA-Ea/RT=lnA-Ea1/RT..+(1/2)*[lnA-Ea2/RT]-lnA+Ea3/RT
So if we have value of A then we can get the value of Ea using the equation.
