There are two molecules with the formula C 3 H 6 Propane, CH 3 CH = CH 2 , is the monomer of the polymer polypropylene, which is used for indoor-outdoor carpets. Cyclopropane is used as an anesthetic: When heated to 499 °C, cyclopropane rearranges (isomerizes) and forms propane with a rate constant of 5.95 × 10 − 4 s − 1 . What is the half-life of this reaction? What fraction of the cyclopropane remains after 0.75 h at 499 °C?
