You're stuck using an old potentiostats that seems to be having problems measuring the nanoamperes of current required for a typical diffusion experiment, so you set aside your UME and make an electrode out of some Pt wire instead.
a. Calculate the steady state current at a flat Pt disk of radius 0.5 mm for the cell.
b. How long do you expect to have to wait to observe the steady state current calculated in (a)? Is this a reasonable or unreasonable experiment? Why?
