What is the electrode potential for Pb^(2+)(aq) + 2e^(-) rightleftharpoons Pb(s) when the concentration of Pb^(2+) (aq) is 0.05 mol dm^(-3) ?
Temperature is 298 K and the standard electrode potential for the half-cell reaction is -0.13 V.

-0.16 V
Explanation:
The expression for the electrode potential of a half - cell is:
For this half - cell at 298K this can be simplified to:
We would expect the potential to become more -ve like this since Le Chatelier's Principle predicts that reducing
