# Answer to Question #282843 in Chemical Engineering for Mayyy

Question #282843

The speed of the butadiene dimerization reaction was investigated by measuring the total pressure in a batch reactor operating isothermally at a temperature of 326 degrees Celsius. The measurement results are as follows:

t (minutes) 0 5 10 15 20 25 30 35 40 45 50 55 60 70

Pt (mmHg) 632 611 552 573.5 558.5 545 533.5 523 514 505 497 490 484 473

Calculate the order reaction and the rate constant for the reaction. Then the equation for the rate of reaction

To find the order of reaction we can use graphic method

Graph is not linear this means butadiene dimerization is not zeroth-order reaction.

Graph is not linear this means butadiene dimerization is not first-order reaction.

Graph is linear this means butadiene dimerization is second-order reaction.

From the graph slop = [k] = 132x103
