Question 1

The first-order decomposition, A → products, has a rate constant of 0.150 s^–1. Starting with [A]_o = 0.350 M, how much time is required for [A]_t = 0.125 M?
◦ 6.86 s
◦ 2.98 s
◦ 34 s
◦ 1.50 s
◦ 4.62 s

Question 2

The following initial rate data apply to the reaction below.
F₂(g) + 2Cl₂O(g) → 2FClO₂(g) + Cl₂(g)

Expt. #	[F₂] (M)	[Cl₂O] (M)	Initial rate (M/s)
1	0.05	0.010	5.0 × 10^–4
2	0.05	0.040	2.0 × 10^–3
3	0.10	0.010	1.0 × 10^–3

Which of the following is the rate law (rate equation) for this reaction?

◦ rate = k[F₂]²[Cl₂O]⁴

◦ rate = k[F₂]²[Cl₂O]
◦ rate = k[F₂][Cl₂O]
◦ rate = k[F₂][Cl₂O]²

◦ rate = k[F₂]²[Cl₂O]²
