Excess of zinc reacts with HCl(aq) in the reaction: Zn(s) + 2HCl(aq, 4.00 M) → ZnCl2(aq, 0.100 M) + H2(g, 0.100 atm)  The immediate amounts of reacting species are: [HCl]0= 4.00 M, [ZnCl2]0= 0.100 M, (PH2)0 = 0.100 atm. The battery, which utilizes the above redox process possesses the following cell diagram: Zn|Zn2+(0.100 M)||H+(4.00 M)|H2(0.100 atm)|Pt. Use the table of standard reduction half-cell potentials in your textbook to calculate: (a) the standard cell potential, Eocell, (b) the immediate cell potential, Ecell, at concentrations and pressures described above, and (c) the immediate Gibbs free energy change for the reaction. Enter your answers with correct units and significant figures.
