when we decrease the concentration of Zn solution, what would happen to the voltage of the electrochemical cells of Zn|Pb ?

[cliverlong]

What are the half-cell equations? Which one is oxidizing and which is reducing? Why?

What are the standard electrode potentials of the half-cells?

What is the significance of the word standard above?

What does Le Chatelier predict about the position of equilibrium if you change the concentration of one electrolyte?

What does such a shift in equilibrium position do to the electrode potential of that half-cell?

What is the effect on voltage of the whole cell?
