Question

The following data represent for the decomposition of NH₄NO₂ in aqueous solution.

Time in minutes	10	15	20	25	∞
Volume of N2 (in mL)	6.25	9.0	11.40	13.65	33.05

(a) Show that reaction is of the first order

(b) Calculate velocity constant.

Answer 1

The volume of N₂ formed at any time is proportional to the amount of NH₄NO₂ decomposed in that time.

Similarly, Culculate K for each case. The values of K come almost  showing that reaction is 1 order. For K, take average of nil value of Λ
