Question

3) A compound known as di-t-butyl peroxide (DTBP) ((CH3)3COOC(CH3)3) decomposes to acetone (CH3COCH3) and ethane according to the reaction given. The total pressure of the reaction mixture changes with time, as shown by the data given at 300 K.

Time (min) P (atm) Time (min) P (atm)

0 0.2362 22 0.3188

2 0.2466 26 0.3322

6 0.2613 30 0.3449

10 0.2770 34 0.3570

14 0.2911 38 0.3687

18 0.3051 40 0.3749

20 0.3122 42 0.3801

46 0.3909

a) Calculate the partial pressure of DTBP at each time from the data. Assume that at time 0 only DTBP is present.

b) Determine the order
