A student prepares a reaction mixture 1 by adding 10.0 mL of 4.0 M acetone, 10.0 mL of 1.0 M HCl , 10.0 mL of 0.0050 M I2, and 20.0 mL of water. The reaction mixture is initially yellow, but after 4 minutes and 22 seconds, the reaction mixture becomes clear indicating that the I2 has been completely consumed in the reaction. The student repeats the reaction (mixture 2) but instead of 10.0 mL of 4.0 M acetone he uses 20.0 mL of 4.0 M acetone and 10.0 mL of water rather than 20. The reaction goes to completion in 2 minutes and 10 seconds.
Acetone + I2 =====(HCl)=====> products
5. Assuming that all of the iodine is consumed in the reaction, what is the average rate of disappearance of I2 in M/s for reaction mixture 1?
6. In reaction mixture 2, the concentration of acetone was doubled and the concentration of I2 and HCl remained the same. What is the average rate of disappearance of I2 in M/s for reaction mixture 2?
7. Comparing the rates of reaction mixture 2 to the rate of reaction mixture 1, what is the exponent of the acetone in the general rate law?
