You are given an unknown transition metal complex that forms a red solution. You find that it reacts with oxidizing agents to yield a colorless solution. You use UV-visible spectroscopy to quantify the rates of reaction with various oxidizing agents. You find that that the reaction rate increases in the order of ClO- < ClO2- < ClO3-. Your research advisor than suggests you next try ClO4-. To your advisors surprise, the reaction with ClO4- is much slower than the reaction with ClO3-. Why is your advisor surprised? Explain to your advisor the results in terms of Marcus theory. Hint: Start by considering the oxidizing powers of the various reagents.
