Transcribed Image Text:In the activity, click on the Eell and Keq quantities to observe how they are related.
Use this relation to calculate Keq for the following redox reaction that occurs in an
electrochemical cell having two electrodes: a cathode and an anode. The two half-
reactions that occur in the cell are
Cu²+ (aq) +2e →Cu(s)
and
The net reaction is
Zn(s) Zn²+ (aq) + 2e¯
Cu²+ (aq) + Zn(s) Cu(s) + Zn²+ (aq)
Use the given standard reduction potentials in your calculation as appropriate.
