Triiodide reacts with acetone in acidic aqueous solution: I3–(aq) + CH3COCH3(aq) CH3COCH2I(aq) + 2 — Kinetics Chemistry Question
Question
Triiodide reacts with acetone in acidic aqueous solution:
I3–(aq) + CH3COCH3(aq) CH3COCH2I(aq) + 2 I–(aq) + H+(aq)
The reaction is carried out twice, both times with [I3–]0 = 1.0 10–3 M and [H+]0 = 1.00 M, but with two different concentrations of acetone, and the concentration of triiodide is found to vary with time as shown:
What are the orders of triiodide and acetone in the reaction?
A.
First-order in I3–, first-order in CH3COCH3
B.✓ Correct
Zeroth-order in I3–, first-order in CH3COCH3
C.
First-order in I3–; the order in CH3COCH3 cannot be determined from the available data
D.
First-order in CH3COCH3; the order in I3– cannot be determined from the available data
