EXERCISE 19.8: Chronoamperometry with a reducing potential was conducted with a 3.05103M solution of a new Rh (phen) L42+ complex using a 1.0mm diameter platinum disk electrode. The slope of the icat versus t1/2 was 3.66 106As1/2. A literature search reveals that the diffusion coefficient of Ru(phen)L42+ is known to be 1.1105cm2/s and the diffusion coefficient of Pd (phen) L42+ is 7.2106 cm2 /s. (Hint: Look at a periodic table.) Give a reasonable estimate of the number of electrons transferred (v) in the chronoamperometric reduction of Rh(phen)L42+. (The term phen refers to the neutral phenanthroline ligand.)
