Question 1

The reaction

exhibits the rate law

where k = 1.0 × 10^–5M^–1 s^–1 at 25°C. This reaction is run where the initial concentration of NOBr ([NOBr]₀) is 0.40 M. What is one half-life for this experiment?

◦ 4.0 s
◦ 2.0 × 10^–5 s
◦ 6.9 × 10^–4 s
◦ 2.5 × 10⁵ s
◦ None of these are correct.

Question 2

The reaction

is first order in N₂O₅. For this reaction at 45^oC, the rate constant k = 1.0 × 10^–5 s^–1, where the rate law is defined as

For a particular experiment ([N₂O₅]₀ = 1.0 × 10^–3M), calculate [N₂O₅] after 4.1 × 10⁵ seconds.

◦ 4.1 M
◦ 1.0 × 10^–3M
◦ 1.7 × 10^–5M
◦ 0 M
◦ 11 M
