Description
LECTURE 15 Slide No. Notes 21 - in the chart, all are reduction half-reactions - when E is greater than zero, reaction is spontaneous - above the highlighted line, favoured reactions - Note that Li+ is not a reducing agent, it is a poor oxidizing agent - Li is the reducing agent 22 - For given reaction, the lower one will occur more readily - Electrons will cancel out - Final overall reaction is spontaneous 23 - the one that must be switched is the more negative one - thus the Zn is switched, as oxidation half-cell - Overall cell potential = 1.56 V (sum of oxidation and reduction potentials) 24 - n = number of moles electrons transferred in reaction - CHANGE: F is PER MOL of electrons - Postive cell potential, negative free energy value - Units cancel so left with only joules - Same thing for standard free energy (the equation with the degree sign) - Ans1: B - Ans2: A - Remember, opposit
