The activation energy for the reaction is 2.29766 kJ
Explanation :
According to the Arrhenius equation,
or,
where,
= rate constant at = k
= rate constant at = 2k
= activation energy for the reaction = ?
R = gas constant = 8.314 J/mole.K
= initial temperature = 200 K
= final temperature = 400 K
Now put all the given values in this formula, we get :
