Calculate the double layer capacitance for the helmholtz layer on a metal if the dielectric
constant within the helmholtz layer is 10 and the thickness of the helmholtz layer is 15 å.
(b) calculate the double layer capacitance for a gouy−chapman layer of dielectric constant 50
and thickness 100 å. (c) use the stern model of the double layer to calculate the total double
layer capacitance, assuming that the inner helmholtz layer and the gouy−chapman layer have
capacitances in series.
