For the following Nernstian half-reaction A3++2eA+,E0=0.5Vvs.NHE il,c=4A and il,a=2.4A with 2mMA3+ and 1mMA+. (a) In the case where you have both the cathodic and anodic limiting current, you can redefine E1/2 as the potential at which the current is half-way in between il,c and il,a. Prove that E1/2=E0nFRTlnmRmO (b) What is the value of E1/2(Vvs.NHE) ? (c) What is the value of E(Vvs.NHE) at zero current? (d) Plot i vs. E
