Butadiene reacts to form its dimer according to the equation

2 C 4H6(g) --> C8H12(g)

The following data were collected for this reaction at a given temperature:

[C4H6] Time ( 1 s)

0.01000 0

0.00625 1000

0.00476 1800

0.00370 2800

0.00313 3600

0.00270 4400

0.00241 5200

0.00208 6200

(a) Determine is the order of this reaction? Write the rate law expression. Justify your answer. Sketch a graph as part of your explanation.   

(b) Determine the value of the rate constant for this reaction?


(c) Determine the half-life for the reaction under the conditions of this experiment?




2nd since plot of 1/[C4H6] vs. time yields a straight line with a |slope| = k = 6.14 × 10−2 M/s; 1630 s

Answer #1

To find out rate of a reaction we have four different methods.

1) Graphical method

2) Half Life method

3) Initial rate method

4) Concentration V/S time method

I use Graphical and Concentration V/S time method simultaneously
