9. The kinetics of the oxidation of ferrodoxin by oxygen were investigated in a careful series of experiments, shown below at 25 °C. 2 Fd[Fe2*] (aq) + O2 (aq) + 2 H* (aq) → 2 Fd[Fe3*] + H:O2 (aq) What was measured was the absorbance of the Fd[Fe2+] at 475 nm after exactly 1 second of reaction, in a 1-cm cuvette. The initial absorbance of the solution at 475 nm was 0.095. Hint, from the decrease in A475 you can calculate how much Fd has reacted. [Fd[Fe2+]]o (uM) [02]o (mM) [H*]o (M) A475 after 1.0o sec 0.065 0.034 0.053 0.036 1.5 1.5 1.5 3. 1.5 0.050 3.0 1.5 1.5 0.050 0.050 0.100 a. Derive the RATE LAW. b.
