Question 1

For the reaction 2N₂O₅(g) → 4NO₂(g) + O₂(g), the following data were collected:

t (minutes)

[N₂O₅] (mol/L)

	0	1.24 × 10^-2
	10.	0.92 × 10^-2
	20.	0.68 × 10^-2
	30.	0.50 × 10^-2
	40.	0.37 × 10^-2
	50.	0.28 × 10^-2

70.

0.15 × 10^-2

The half-life of this reaction is approximately:

Reference: Ref 12-10

◦ 15 minutes
◦ 18 minutes
◦ 23 minutes
◦ 36 minutes
◦ 45 minutes

Question 2

For the reaction A → Products, successive half-lives are observed to be 10.0 min and 40.0 min. The reaction follows the integrated rate law.

Reference: Ref 12-13

◦ [A] = –kt + [A]₀
◦ ln [A] = –kt + ln [A]₀
◦

= kt +

◦

= kt +

◦ None of these are correct.
