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 hundreths of a second read 01:42:01, the time would be reported as 102.01 seconds Report Table IC.1: Reaction Times Reaction times for experiments A1-A7 Reaction time (s) A1 1125 A2 610 A3 325 A4 545 A5 329 A6 259 AZ 114 Report Table IC.2: Reaction Times for Hot and Cold Solutions Measurements of temperature and initial rates for reactions A3 cold and Azhot Temperature (C) Reaction time 1 (s) Reaction time 2 (s) A3 cold 52 1290 1301 A3 hor 45.5 78 179 (39pts) Initial Rates Complete the following table by calculating the initial concentration of reagents.
