Given the chlorination of acetone shown below, choose the correct rate law.
CH3COCH3 + Cl2 → CH3COCH2Cl + HCl
A) rate = [CH3COCH3]
B) rate = [Cl2]
C) rate = [CH3COCH3][Cl2]
D) rate = [CH3COCH3][Cl2]1/2
E) cannot be determined from stoichiometry; must be determined experimentally
Rate Law
An equation that relates the rate of a chemical reaction to the concentration of its reactants, often in the form rate = k[A]^x[B]^y, where k is the rate constant.
Chlorination
A chemical process that introduces chlorine atoms into a molecule.
Acetone
A volatile, colorless liquid used as a solvent and an antiseptic; it's the simplest and most important of the ketones.

Final Answer :
E
Explanation :
The rate law for a chemical reaction cannot be determined solely from the stoichiometry of the reaction; it must be determined experimentally because it depends on the mechanism of the reaction, which is not provided by the stoichiometry.
