Using the Arrhenius Equation k = Ae-Ea/RT Ink = In A- Ea 1 RT so for k at two different temperatures: In K1 a RT2 = For experiment 8, k = 1/time. The plot with 1/T (K) as the independent variable and In(k) as the dependent variable yields a straight line with slope - Ea/R, which can be solved for Ea. Select a data point, use one of the forms of the Arrhenius equation and solve for A. Since you now have both E, and A, you could predict how long the reaction should take at different temperatures, or what temperature would be required to see the blue starch - iodine. color in a particular amount of time. But, before doing that it is best to compare what the Arrhenius equation would 'predict' for the rate at your experimental temperatures. Do this by plugging in your calculated activation energy and value for A into the Arrhenius equation using your experimental temperatures and solving for the rate constant.
