A student is given the electrochemical cell reaction:MnO4-(aq) + 8H+(aq) + 5e- → Mn2+(aq) + 4H2O(l)Calculate the standard potential (in volts) of the cell at 25°C given that the standard reduction potential of MnO4-(aq)/Mn2+(aq) couple and the standard reduction potential of the H+(aq)/H2(g) couple are +1.51 V and 0.00 V, respectively. The concentration of MnO4-(aq) is 0.010 M and that of H+(aq) is 1.00 M.
