123. Solving a chemistry problem

3. Make diagrams of working galvanic cells using the proposed electrodes:
Fe | Fe2 ,Zn | Zn2 , Pt, H2| 2H 1. Write the equations of the processes occurring on the anode and cathode in these elements, the equations of current-generating reactions. Calculate the values of electrode potentials at: С cathodic electrolyte = 0.1 mol/l, С anode electrolyte = 0.01 mol/l.
Calculate the value of the electromotive force of the galvanic cell and the Gibbs energy of the current-forming reaction.
