The Latimer diagram for Fe, at pH = 0, is shown below: Fe4+ +1.21V Fe+ +0.77V What is the most stable oxidation state? Fe+ What is the least stable oxidation state? -0.44V Calculate the -AG/F values for Fe4+, Fe+, Fe+ and Fe at pH = 0 and draw the Frost-Ebsworth diagram of Fe with the values obtained. Fe Is Fe+ stable with respect the disproportion reaction to form Fe4+ and Fe+? Which of the following reactions are spontaneous? Explain your answer determining the AG/F for the following semi- reactions: Oxidation from Fe+ to Fe+; Oxidation from Fe to Fe+; Reduction from Fe+ to Fe+. Determine the E values for the following reactions: Fe+ + 3e Fe Fe4+ + 2e Fe+
