Pleae the problem in detail. The subject I am learning is electrochemistry.

3. Electrochemistry exam. (10 points) (1) Agcl(s)+e(Ag)Ag(s)+cl(aq) (2) H++e(Pt)21H2(g) (a) Find G~ and express the null potential En in terms of G and activity. (b) When there is an outside circuit and current flows. plot current I versus E curve. In the y axis, indicate which part is the galvanic current and the electrolytic current
