Question 1

The first-order decomposition of N2O5 at 328 K has a rate constant of 1.70 × 10-3 s-1. If the initial concentration of N2O5 is 2.88 mol L-1, what is the concentration of N2O5 after 12.5 minutes?
◦ 2.82 mol L-1
◦ 0.355 mol L-1
◦ 0.174 mol L-1
◦ 0.124 mol L-1
◦ 0.805 mol L-1

Question 2

The second-order decomposition of NO2 has a rate constant of 0.255 L mol-1 s-1. How much NO2 decomposes in 4.00 s if the initial concentration of NO2 (1.00 L volume) is 1.33 mol L-1?
◦ 0.56 mol
◦ 1.8 mol
◦ 0.77 mol
◦ 0.85 mol
◦ 0.48 mol
