Question

A researcher designed an experiment to investigate the mechanism of the following reaction The reaction progress was monitored at set time intervals and the concentration of each of the chemical species A, B, and C was measured. The results of the experiment performed at 22°C are summarized in the table below Experiment [A]o (M)[Blo (M)[Clo (M) Initial rate (M/s) 1.47x102 7.33x 102 2.54x 102 5.35x10-10 1.47x10-27.33x 10-25.16x10-22 1.47×10-2 | 1.36x10-1 | 5.16×10-2 5.83×10-2 | 1.36×10-1 | 5.16×10-2 2.21 x10-9 2.21x10-9 3 8.76x10-9 (a) Determine the rate law for the reaction. chemPad Help Greek (b) Calculate the rate constant for the reaction.

Explanation / Answer

with respect to A reaction is first order.

with respect to B reaction is zero order

with respect to C reaction is second order

rate law as follows

rate = K [A] [C]2

b) K = rate / [A] [C]2

K = 5.35 x 10-10 / [1.47 x 10-2] [2.54 x 10-2]2

K = 5.35 x 10-10 / 9.48 x 10-6

K = 5.64 x 10-5 M-2 s-1
