Chapter 11 - Redox Rxns and Electrochem

Electrochemistry study of relationship btwn chem rxns and electrical E
Electrochemical rxns include spontaneous rxns that produce electrical E and nonspontaneous rxns that use electrical E to produce chemical change
redox rxn coupled oxidation and reduction rxns occuring simultaneously
oxidizing agent gets reduced and causes another atom to be oxidized; NAD+
reducing agent gets oxidized and causes another atom to be reduced; NADH
Oxidation Numbers assigned to atoms to keep track of redistribution of e- during chemical rxn
Electrochemical cells contained systems where redox rxns occur
Galvanic Cell where spontaneous rxns occur; G is negative, energy used to do work
Electrolytic Cell where nonspontaneous rxns occur; positive G
Anode where oxidation occurs
Cathode where reduction occurs
charge of e- 1.6E-19 C
Faraday's Constant 96,487 C/mol e-
reduction potential tendency of a species to acquire e- and be reduced
standard electromotive force (emf) difference in potential btwn two half-cells
If emf is positive then G is negative, ln K is positive, products are favored, and rxn is spontaneous
