Question

Consider the following reaction: CH₃X + Y -> CH₃Y + X and the experimental data below:

The graph of 1/[CH₃X] versus time was found to be linear.
The magnitude of the rate constant at 85°C was measured to be 7.88 x 10⁸(time units = hours)
The following initial rates data were collected at 25°C:

Experiment	[CH₃X]_o (M)	[Y]_o (M)	Rate (M/hour)
1	4.50 x 10^-3	3.00	5.06 x 10^-3
2	4.50 x 10^-3	4.50	7.58 x 10^-3

(a) Determine the rate law including the value of k with the appropriate units.

(b) Determine the activation energy for this reaction.
