Two reactions have identical values for Ea. Does this ensure that they will have the same rate constant if run at the same temperature?
We have to determine if two reactions with the same activation energy would have the same rate constants if they are run at the same temperature.
We will use the two-point form of the Arrhenius equation to solve this problem.
Where,
k1 = rate constant at T1
k2 = rate constant at T2
Ea = activation energy
R = universal gas constant
T2 = higher temperature
T1 = lower temperature
