Hello,
I read on wikipedia that the second law represents how concentration changes with time, but I was wondering how taking the partial derivative with respect to x of the first law will give change in concentration with time?

See here, for example:
http://en.wikipedia.org/wiki/Fick's_laws_of_diffusion It's not that you get the second law just by taking the derivative of the first law. Conservation of mass is used as well.
