Question

Use your experiment rate law and the average value for k to predict how long (in seconds)
it would take for the acetone iodination reaction to finish for the initial conditions given
below. Note that you are solving for Δt in the average reaction rate.
initial concentrations: [acetone] = 0.850 M
[H+] = 0.320 M
[I2] = 0.00150 M
reaction time (seconds): ______________

How precise were the experimental measurements of the reaction time for each reaction
mixture? How precise were the measurements of the value of the rate constant, k? Explain your answers.

Determining the Rate Law for the Iodination of Acetone
• the volumes used for all eight reaction trials (two trials for each reaction mixture) match the volumes
given in Table 2 below:
