Question

A) in a reaction involving the iodination of acetone, the following volumes were used to make up the reaction
mixture:
10 mL 4.0 M acetone + 10 mL 1.0 M HCl + 10 mL 0.0050 M I₂ + 20 mL H₂O

What is the total volume of the sample?

V = ___ mL

B) In a reaction involving the iodination of acetone, the following volumes were used to make up the reaction
mixture:
10 mL 4.0 M acetone + 10 mL 1.0 M HCl + 10 mL 0.0050 M I₂ + 20 mL H₂O

What is the initial concentration of acetone in the mixture?

[acetone] = ___ M

C) Which recipe below will double the initial concentration of acetone , while holding the concentrations of H⁺ and I₂ the same as in the above problems?

D) Using the recipe,

10 mL 4.0 M acetone + 10 mL 1.0 M HCl + 10 mL 0.0050 M I₂ + 20 mL H₂O

Lola found that it took 230 seconds for the color due to I₂ to disappear. What was rate of the reaction based on these starting conditions?

rate = ___ M/s

E) A second run is made using the following recipe:

10 mL 4.0 M acetone + 20 mL 1.0 M HCl + 10 mL 0.0050 M I₂ + 10 mL H₂O

This time, Lola saw that the reaction took 115 seconds for the color due to I₂to disappear. What is the reaction rate for this run?

rate = ___ M/s

F) Based on the data given in questions D and E, what is the order of the reaction with respect to H⁺?
