A Flask containing 10ml of 0.010 M KI, 10ml of 0.0010M Na2S2O3, and 10ml H2O are mixed with another flask containing 10ml of 0.040M KBrO3, 10ml of 0.10M HCl and 3 drops of starch to create a reaction. This reaction is repeated in 4 trials at different temperatures. The first trial at 20C, the second at 43C, the third at 33C and the 4th at 6C. We take note of when this reaction goes from a clear solution to a blue color and time it. The first trial took 191s, the second took 37s, the third took 81s and the 4th took 557s. We are given the Observed rates of all 4 trials and are required to find the In(Rate) as well as the 1/Temp reciprocal k using the Arrhenius equation. Trial 1 Rate = 5.24*10^-7 Trial 2 Rate = 2.70*10^-6 Trial 3 Rate = 1.24*10^-6 Trial 4 Rate = 1.80*10^-7

Question
A Flask containing 10ml of 0.010 M KI, 10ml of 0.0010M Na2S2O3, and 10ml H2O are mixed with another flask containing 10ml of 0.040M KBrO3, 10ml of 0.10M HCl and 3 drops of starch to create a reaction.
This reaction is repeated in 4 trials at different temperatures. The first trial at 20C, the second at 43C, the third at 33C and the 4th at 6C. We take note of when this reaction goes from a clear solution to a blue color and time it. The first trial took 191s, the second took 37s, the third took 81s and the 4th took 557s.
We are given the Observed rates of all 4 trials and are required to find the In(Rate) as well as the 1/Temp reciprocal k using the Arrhenius equation.
Trial 1 Rate = 5.24*10^-7
Trial 2 Rate = 2.70*10^-6
Trial 3 Rate = 1.24*10^-6
Trial 4 Rate = 1.80*10^-7
