Asked by Mohamed
The decomposition of hydrogen peroxide in solution and in the presence of iodide ion was studied in laboratory, and the following mechanism proposed based on the experimental data.
H2O2 + I - = H2O + IO - (slow)
H2O2 + IO - = H2O + O2 + I - (fast)
Which one of the following statements is false?
a. The reaction is first order with respect to H2O2.
b. The reaction is first order with respect to I -
c. I - is a catalyst.
d. IO - is an intermediate.
e. More than one statement is false (or none of the statements are false).
I think its E (none are false)
H2O2 + I - = H2O + IO - (slow)
H2O2 + IO - = H2O + O2 + I - (fast)

I think it is b. From the wording of the question, it appears to me that I^- is a catalyst. If that is true, the concn I^- will not matter.
