Worksheet: Half-Lives from Reaction Data
In this worksheet, we will practice calculating half-lives of first- and second-order reactions from measurements of concentration over time.
Compound spontaneously decomposes in solution. At the beginning of the reaction, compound has a concentration of 0.2330 M and a half-life of 11.98 min. The concentration of after a time is 0.0870 M.
If the decomposition of is a first-order reaction, what is the value of , to 3 significant figures?
If the decomposition of is a second-order reaction, what is the value of , to 3 significant figures?
