Calculate the limiting current for the hydrogen half-reaction, h+(aq) + e- = (1/2) h2(g), which takes place at an rde in hcl(aq) solution with ph=4 at 25 oc and 1 bar (latex: \nu ν = 10-6 m2/s), at an angular velocity of 100 rad/s. the diffusion coefficient of proton can be found in chapter 10: data section.
