2. from your results in part A, calculate the time for the blue color to appear for this system if 1.5 mL KI, 1.5 mL KCL, 1.0mL (NH4)2S2)8 and 1.0mL Na2S2O3 from Table 15-1 are mixed.

4. Use your data from experiments 2,4,5 and the Arrhenius Equation

log k2/k1=Ea/2.303R(T2-T1/T2T1)

to calculate the value of Ea for this reaction. How does this value compare with that obtained from the slope of the plot? Which one do you think is more accurate? Explain.

5. Do your data agree with the postulate that the reaction rate will double for a 10 degrees Celcius rise in temperature? Support your answer with a calculation.
