One-Particle Model with Square Potential-Energy Wells

1 One-Particle Model with Square Potential-Energy Wells 

The average time for a particle in an activated state to cross the activation barrier is 

In a system of N particles, the total rate at which particles cross the barrier, 

Consider a total time r ta, where ta is the time that a particle spends in an activated state. Then, 

The ratio of times spent in a well state and in an activated state is
