Question 1

The reaction A → products is first order. If the initial concentration of A is 0.391 M and, after 16.2 seconds have elapsed, the concentration of A has fallen to 0.0284 M, what is the rate constant of the reaction?

◦ 0.162 s–1

◦ 0.0428 s–1

◦ 0.0224 s–1

◦ 2.02 s–1

◦ 0.0617 s–1


Question 2

The reaction A → products is second order. If the initial concentration of A is 0.419 M and, after 26.6 seconds have elapsed, the concentration of A has fallen to 0.0231 M, what is the rate constant of the reaction?

◦ 0.109 M–1 s–1

◦ 1.54 M–1 s–1

◦ 0.0261 M–1 s–1

◦ 0.0149 M–1 s–1

◦ 0.0376 M–1 s–1
