Worksheet: First-Order Reaction Half-Lives
In this worksheet, we will practice interpreting and converting between the half-lives and rate constants of first-order reactions.
When heated to , cyclopropane () reacts to form its structural isomer propene with a rate constant of .
Calculate the half-life of this first-order reaction.
Calculate the percentage of cyclopropane remaining after 0.750 h, to two significant figures.
Calculate the ratio of cyclopropane to propene after 0.434 h, to two significant figures.
