Constants

The following values may be useful when solving this tutorial.

Constant	Value
E∘Cu	0.337 V
E∘Ni	-0.257 V
R	8.314 J⋠mol−1⋠K−1
F	96,485 C/mol
T	298 K

Part A

In the activity, click on the E∘cell 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 Ni(s)→Ni2+(aq)+2e−

The net reaction is

Cu2+(aq)+Ni(s)→Cu(s)+Ni2+(aq)

Use the given standard reduction potentials in your calculation as appropriate.
