Experiment for Kinetics – The Iodine Clock Reaction Results A1: Trial 1: took 43.64 seconds to turn from clear to purple, trail 2: took 44.82 seconds to turn purple, trail 3: which was 47.49 seconds to turn purple, trail 4: was 45.23 seconds to turn purple again, and lastly trail 5: which was 43.63 seconds to turned from clear to purple. Results A2: Trial 1: took 55.10 seconds to turn from clear to purple, trail 2: was 52.77 seconds to turn purple, trail 3: which was 44.67 seconds to turn purple, trail 4: was 59.69 seconds to turn purple again, and lastly trail 5: which was 54.88 seconds to turned from clear to purple. Results A3: Trial 1: took 76 seconds to turn from clear to purple, trail 2: was 88 seconds to turn purple, trail 3: which was 102 seconds to turn purple, trail 4: was 82 seconds to turn purple again, and lastly trail 5: which was 93 seconds to turned from clear to purple. Results A4: Trial 1: took 206.31 seconds to turn purple, trail 2: was 188.55 seconds to turn purple, trail 3: which was 177.13 seconds to turn purple, trail 4: was 199.36 seconds to turn purple again, and lastly trail 5: which was 172.56 seconds to turned from clear to purple. a. Calculate the [I-] and [S2O82-] after mixing using the dilution equation (M1V1 = M2V20). Record the concentrations in your data table.b. Calculate the reaction rate for each of your measured times in M/s using the relationship:rate = 6.30 x 10−4M/∆tc. Using your calculated concentrations and rates, determine the order of reaction withrespect to I-.
