Not the precise answer, but you could think this way:

Optimize the reactant and the transition state, calculate the reaction energy barrier (denotes E)..

let R*T ~= E, you can solve it for T..

More precisely:
Optimize the reactant and the transition state, meanwhile calculate thermo properties, then write the the reaction energy barrier at temperature T as E(T), a function of temperature.
let R*T = E(T), you can also solve it to get T..

Sorry if my method could be wrong, you better look up some literature, I was just talking to myself..
