The Arrhenius Equation
Arhenius discovered that most reaction-rate data obeyed an equation
based on three factors:
(1) The number of collisions per unit time.
(2) The fraction of collisions that occur with the correct orientation.
(3) The fraction of the colliding molecules that have an energy
greater than or equal to Ea.
From these observations Arrhenius developed the aptly named
Arrhenius equation.
