An electrochemical cell is constructed such that on one side a pure Zn electrode is in contact with a solution containing Zn2+ ions at a concentration of 10–2 M. The other cell half consists of a pure Pb electrode immersed in a solution of Pb2+ ions that has a concentration of 10–4 M. At what temperature will the potential between the two electrodes be +0.568 V?

What? i don’t understand

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

Idon't know hope someone you
