Question

Which reduction is easier?

(a) Fe(III) to Fe(II)
(b) Cu(II) to Cu(I)
under STP(standard pressure and temperature) conditions.Please specify answer with reason​

Answer 1

Reduction of Cu II TO Cu I is easier than Fe III to Fe II. It is very clear if you run a TPR run of these samples if you....It relates to the standard oxdn redn potentials for each of these metals/stages. Cu II to Cu I will take place at around 200oC, where as Fe III to Fe II will occur above 400oC (in pure form).

follow me !

Answer 2

b) Cu(II) to Cu(I) Copper reduction is easier
