Question 4
Two mechanisms are proposed:
$H_2O_2 + I^- \rightarrow H_2O + OI^-$
$OI^- + H^+ \rightarrow HOI$
$HOI + I^- + H^+ \rightarrow I_2 + H_2O$
$I_2 + I^- \rightarrow I_3^-$
$H_2O_2 + I^- + H^+ \rightarrow H_2O + HOI$
$HOI + I^- + H^+ \rightarrow I_2 + H_2O$
$I_2 + I^- \rightarrow I_3^-$
Which mechanism and which step as the rate determining step would best fit the
data?
Select one:
Mechanism I, with the first step the rate determining step.
Mechanism I, with the second step the rate determining step.
Mechanism II, with the first step rate determining.
Mechanism II, with the second step rate determining.
