Diffusion as a probability for a random walk - please see the attached question.
No big derivation is required and this may be able to be answered in just a few lines.
The main point is to show the probability of hopping using only the values given at the bottom of the attached pdf.© BrainMass Inc. brainmass.com October 10, 2019, 5:28 am ad1c9bdddf
Please see the attached file for the complete solution.
Our model of diffusion in one dimension consists of a grid with N slots (N is assumed to be large), each containing a finite number of particles, each slot labeled with an index k running from 1 to N. The spacing of the slots is (please see the attached file) which is assumed to be small. After each small time interval a particle has a small probability p of jumping from slot k to slot The grid contains (please see the attached file) particles in slot k at time interval l. From this ...
In this solution we derive the one-dimensional diffusion equation using basic properties of a random walk. Response includes Microsoft Word attachment.
