Determining Reaction Orders Refer to the volumes in Table IC. 1 when preparing the reagents for experiments A1-A7. Table IC.1: Solution Aliquots for Method of Initial Rates Exp 0.0180 M KI A1 1.00 mL 0.00100 M Na2S2O3 1.00 mL 0.180 M HCI 1.00 mL 1.00 mL 1.00 mL Dl water 5.00 mL 4.00 mL 3.00 mL 4.00 mL 1% starch 1.00 ml 1.00 mL 1.00 mL A2 1.00 mL 2.00 mL 3.00 mL 1.00 mL A3 1.00 mL 0.0720 M NaBroz 1.00 mL 1.00 mL 1.00 mL 2.00 mL 3.00 mL 1.00 mL 1.00 mL A4 1.00 ml 1.00 mL 1.00 mL 1.00 mL A5 3.00 mL 1.00 mL 1.00 mL A6 1.00 mL 1.00 mL 1.00 mL 4.00 mL 2.00 mL 3.00 mL 1.00 mL 1.00 mL 1.00 mL 1.00 mL A7 3.00 mL Temperature of reagents (°C) 80.2 Note: Most stop-watches either report time in the format minutes seconds or in the format minutes seconds:hundredths of a second. You will be entering time in seconds. For example if a stop-watch that reported time to the second read 01:42, the time would be reported as 102 seconds. Whereas if a stop-watch that reported time to the hundredths of a second read 01:42:01, the time would be reported as 102.01 seconds.
