A$.$ To study the formation in the cathode, CV and RDE measurements were conducted. All measurements were conducted with the same electrode and with the same solution $($with mixing in between$).$ Unfortunately, some data was lost due to a computer crash. Calculate the diffusion coefficient and the concentration of chlorin in the solution based on the following graphs $-(20$ points$)$

$$ The radius of the electrode is $0\mathrm{.}085$cm

$$ T$=298$K

$$ The scanning speed is $75$mV$/$s

$$ The kinematic viscosity is $\backslash$upsilon $=0\mathrm{.}01$ cm$2/$s

$$ In the RDE measurement, a current of $0\mathrm{.}41785$mA was measured for a rotation speed of $600$RPM$.$

B$.$ What would you suggest to solve the problem in section E$.$ Consider the electrode material, the electrolyte, etc. $(5$ points$)$
