1. A student prepared the following mixtures and measured the time each took to react. Calculate the average time for each mixture (in seconds). Mixture Vol. of 4.0M acetone (ml) 1 2 10 20 10 10 Vol. of 1.0M HCI 2222 Vol. of 0.0050M 1, 10 10 10 5 Vol. of H₂O (ml) 20 10 10 25 Time for Trial 1 249 123 121 124 Time for Trial 2 251 125 124 126 Average time (s) 2. To complete the following table: a. Determine the initial concentration (molarity) of each reagent using the equation (note: these values will be exactly the same for your experimental data): Man Vis MetaVital The Man and Vfor each reagent are given in problem 1 (fpr example, for acetone, the Maxis 4.0 M and Vis 10 mL for mixture 1). The total volume is 50 mL for each trial. b. Calculate the rate of the reaction using the equation (note: these rates may differ slightly from the data collected during your experiment) rate=LLL
