Consider the following electrochemical cell: Co (s) | Co2 (aq, 1.00 M) || Pb2 (aq, 1.00M) | Pb (s) What will the potential (in volts, V) of the cell be if it is allowed to run until the concentration of the transition metal in the cathode is 0.45 M

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Ithink its called the coefficent.
