Chapter 19: Electron Transfer Reactions
Main Concepts:
1.Redox Reactions consist of two halves,Oxidation and Reduction
2.Reaction Potential, Erxn, in Redox Reactions
3.Nernst Equation adjusts Eorxn to make Erxn
4.Electrochemical Cells (in two flavors) used to get useful work from redox reactions
Electron Transfer Reactions
Reaction Potential, Erxn, in Redox Reactions• How does this relate to Free Energy?• How do you write redox reactions?• How can you predict spontaneous redox
reaction?
Let’s watch one in action!
Electron Transfer Reactions: contrast to Acid/BaseAH + B A- + BH+
thermodynamics
Acid: H+ donor K: extent of forward rxn
Base: H+ acceptor G = -RTlnKG < 0, spont.
acid strength: Ka
base strength: Kb
Acid/base reactions occur in pairs:need an acid and a base,a H+ donor and a H+ acceptor
Electron Transfer Reactions: parallels to Acid/Base
