Question 1

Calculate rate constant k for a first order reaction with a half-life of 75.0 min.
◦ 52.0 min-1
◦ 1.54 × 10-4 min-1
◦ 1.33 × 10-2 min-1
◦ 9.24 × 10-3 min-1
◦ 2.67 × 10-2 min-1

Question 2

Carbon-14, which is present in all living tissue, radioactively decays via a first-order process. A one-gram sample of wood taken from a living tree gives a rate for carbon-14 decay of 13.6 counts per minute. If the half-life for carbon-14 is 5720 years, how old is a wood sample that gives a rate for carbon-14 decay of 11.9 counts per minute?
