Consider the following reaction: CH3X + Y → CH3Y+X At 25°C the following two experiments were run, yielding the following data: Experiment 1: [Y], 3.0 M [CH3 X] Time (h) 7.08 x 10-3 M 1.0 4.52 x 10 -3 M 1.5 2.23 x 10 -3 M 2.3 4.76 × 10-4 M 4.0 -5 8.44 × 10 M 5.7 2.75 х 10° -5 M 7.0 Experiment 2: [Y], = 4.5 M [CH;X] Time (h) -3 4.40 × 10 1.73 x 10 -3 M 1.0 4.27 x 10 -4 2.5 1.05 x 10 -4 4.0 2.60 x 10 -5 5.5 Experiments were also run at 67°C. The value of the rate constant at 67°C was found to be 3.55 × 10° (with the time in units of hours), where [CH3X. 1.0 x 10-2 M and Y], = 3.0 M. a Determine the rate law and the value of k for this reaction at 25°C. (Use k for the rate constant.) Rate = k=
