WebFeb 12, 2024 · In first order reactions, the units of the pre-exponential factor are reciprocal time (e.g., 1/s). Because the pre-exponential factor depends on frequency of collisions, it is related to collision theory and transition state theory. (6.2.3.6.1) k = A e E a / R T. The Arrhenius equation introduces the relationships between rate and A, E a, and T ... WebQuestion.
