Question 1

At a given temperature, a first-order reaction has a rate constant of 1.5 × 10–3 s–1. The time required for the reaction to be 32% completed is

◦ 13 min
◦ 1.9 min
◦ 47 min
◦ 4.3 min
◦ 39 min

Question 2

At a particular temperature, N2O5 decomposes according to a first-order rate law with a half-life of 3.0 s. If the initial concentration of N2O5 is 1.0 × 1016 molecules/cm3, what will be the concentration in molecules/cm3 after 15.5 s?

◦ 2.8 × 1014

◦ 3.3 × 101

◦ 1.0 × 1016

◦ 1.5 × 1014

◦ 2.3 × 10–1
