Spontaneity of Redox Reactions

To a chemist, electrochemical cells are of interest primarily for the information they yield CENGAGENOW concerning the spontaneity of redox reactions, the strengths of oxidizing and reducing Click Chemistry Interactive for a self-study... 

Calculate cell potentials and determine the spontaneity of redox reactions. 

The most important application of electrode potentials is the prediction of the spontaneity of redox reactions. Standard electrode potentials can be used to determine the spontaneity of redox reactions in general, whether or not the reactions can take place in electrochemical cells. 

Standard reduction potentials show the relative likelihood of half-cell reduction reactions and can be used to predict the products, direction, and spontaneity of redox reactions between various substances. 

I Identify the parts of a voltaic cell, and explain how each part operates. I Calculate cell potentials, and determine the spontaneity of redox reactions. 

We can generalize the relationship between the value of E°gd and the spontaneity of redox reactions The more positive the E°gd value for a half-reaction, the greater the tendency for the reactant of the half-reaction to he reduced and, therefore, to oxidize another species. In Table 20.1, for example, F2 is the most easily reduced species, so it is the strongest oxidizing agent listed.
