Inter-arrival time vs number of molecules for diffusion model 1 Inter-arrival time of diffused molecules for molecular concentrations ≃ 10^{–9}, 10^{–6}, 10^{–5}, 10^{–4} moles respectively governed by Model 1. This model as stated earlier is suitable
for diffusion of uncharged molecules. The figure shows that the inter-arrival time
increases with increasing number of molecules diffused in. This is because the concentration
gradient reduces with more molecules diffusing in, resulting in larger time required
for the molecules to move in. Also, it is observed that larger the initial concentration,
the lesser is the inter-arrival time. This is expected due to a higher concentration
gradient. This inter-arrival time distribution can be easily fitted to an exponential
distribution.
