question_answer 29)

For the decomposition of azoisopropane to hexane and nitrogen at 543 K, the following data is obtained. (CH3)2 CHN = NCH (CH3)2  N2 + C6H14

t (sec)	0	360	720
Pressure (atm)	35.0	54.0	63.0

Calculate the rate constant.  

Answer:

The decomposition reaction is of gaseous nature and expression of the rate equation for the reaction is: Rate constant after 360 s i.e. Rate constant after 720 s i.e. = 2.24 × 10?3s?1
