Document Summary

If the net cell voltage e is > 0 then the net cell reaction ill be spontaneous in the forward direction. If the net cell voltage e is <0 then the net cell reaction will be spontaneous is the reverse direction. 38 problem: [agno3(aq)] = 0. 50 [cd(no3)2(aq)] = 0. 010 m 1. Write the half-reaction and eo for both half cells anode cathode by convention, write both as reduction reactions (even though one is not) --> this allows for faster look up in the table of standard reduction potentials39 2. Write the nernst equation for each half-cell cathode anode squared because there are 2 ag ions40 3. Biochemistry and formal reduction potential (e ") reduction potential values measured at ph = 7 instead of ph =0: potentials do not change from the normal ones in reactions that do not involve hydronium ions.
