To "linearize" means take an expansion to its linear term. I am still stuck on this. Any help would be great.

I know on a basic level that the second law says how a concentration will change with time, so that makes sense. Since I know the probability for a molecule to disappear (changing the concentration) is kdt is it as simple as adding this factor on to Fick's law?

Homework Statement Need to linearize the poisson-boltzmann equation to be used later in the problem. I simply have never linearized an equation and searching google didn't really help me understand.Homework Equations http://img215.imageshack.us/img215/2149/eqnq.jpg The Attempt at a Solution...

Homework Statement In a tube filled with a dissolved substance, there is a probability for each molecule to disappear in time dt equal to kdt. Write an equation for dc/dt for the case in which c is not spatially uniform. Homework Equations When concentration is spatially uniform...
