Let the following anodic and cathodic reactions be, respectively: M = M+2 + 2e; EM =-0.941 VSCE ioM = 10-2µA/Cm2

2H+ + 2e = H2 EH =-0.200 VSHE ioH = 0.10 µA/cm2

where icorr = 102 µA=cm2 and Ecorr =-0:741 VSCE

a) Construct the corresponding kinetic diagram.

b) determine bothβa and βc from the diagram and from the defenition of overpotential equations..
