Question

The experimental data for decomposition of N₂O₅

in gas phase at 318K are given below:

t(s)	0	400	800	120 0	160 0	200 0	240 0	280 0	320 0
	1.6 3	1.3 6	1.1 4	0.93	0.78	0.64	0.53	0.43	0.35

(i) Plot [N₂O_5] against t.
(ii) Find the half-life period for the reaction.
(iii) Draw a graph between log [N₂O₅] and t.
(iv) What is the rate law?
(v) Calculate the rate constant.
(vi) Calculate the half-life period from k and compare it with (ii).
