Multiple Choice
Under certain conditions the reaction H2O2 + 3I- + 2H+ I3- + 2H2O occurs by the following series of steps:
k1
Step 1.
H2O2 + H+ H3O2+
k-1 Step 2.
H3O2+ + I- H2O + HOI
(slow,rate constant k2)
Step 3.
HOI + I- OH- + I2
(fast,rate constant k3)
Step 4.
OH- + H+ H2O
(fast,rate constant k4)
Step 5.
I2 + I- I3-
(fast,rate constant k5)
-Which of the steps would be called the rate-determining step?
A) 1
B) 2
C) 3
D) 4
E) 5
