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 45oC, 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
