What is the correct Arrhenius equation?
The Arrhenius equation is, k=Ae−Ea/RT.
The Arrhenius equation shows us how the rate constant depends on those variables.
The Arrhenius equation is k = Ae^-(Ea/RT).
As temperature increases, the rate constant increases, and as Ea increases, the rate constant decreases.
A is the frequency factor, or pre exponential factor.
How do you calculate the Arrhenius equation?
The Arrhenius equation is k = Ae^(-Ea/RT), where A is the frequency or pre-exponential factor and e^(-Ea/RT) represents the fraction of collisions that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea) at temperature T.
