Part B
The iodination of acetone, CH3 COCH3,
aqueous solution is catalyzed by the hydrogen ion
H+:
in
What is the rate constant at 25.0 °C based on the data collected for trial B?
Express your answer numerically in inverse molarity seconds using two significant
figures.
H
I2 + CH3 COCH3
HI + CH3 COCH2I
• View Available Hint(s)
The reaction can be followed visually by adding
starch. The purple starch-iodine complex forms
immediately, then disappears when the iodine has
been consumed. The kinetics of the reaction may be
determined by recording the time required for the
color to disappear, which is the time required for the
iodine, I2, to be consumed.
