Experiment 2 given: rate k[H;O:]'[I]'[H']° Sol'n # Water (mL) 0.050 M 0.1 % 0.050 M 0.050 1.033M Time Тemp (°C) KI (mL) starch NazS201 (mL) 1.000 1.000 M HCI H2O2 (s) (mL) 1.000 1.000 (mL) 1,000 (mL) 2.000 1 16.0 4.00 126.4 25.1 2. 15.0 3.00 2.000 3.000 112.5 25.1 a. Find k (with units) for both trials. b. Use the average k (found in part one) and this second data point at a different temperature to determine the activation energy using the two-point formula: At 55.2°C, k= 0.052 M's'. G. Calculate the rate for each mixture, the rate constant for each mixture, and E, for the reaction.
