Dr. Lori Petrovich11/02/04Spontaneous Net Redox ReactionsInstructions for recognizing and writing spontaneous net redox reactions.1.Look for your potential reactants in the standard reduction potentials in Table 11.1,page 258 of the textbook.Write out the reduction ½ reactions which have yourreactant in them, as either the oxidizing agent or reducing agent.Put the morenegative reduction ½ reactions on top.2.Draw orbitals on the oxidant side (left) which are empty, and orbitals on the reductantside(right) which have electrons in them.3. CIRCLE WHAT YOU HAVE.(Very important:It can’t react if you don’t have it.Some problems have “no reaction” as an answer.)4.Select the pair of reduction ½ reactions in which electrons travel from high energyorbitals to low energy vacant orbits.If electrons cannot travel downhill, there is nospontaneous net redox reaction.Your job is done.If you can spot a reaction,continue.If you spot more than one reaction, chose the one with the greatest Eocell,
