For a first-order reaction, the half-life is constant. It depends only on the rate constant k k and not on the reactant concentration. It is expressed as t1/2=0.693k t 1 / 2 = 0.693 k For a second-order reaction, the half-life depends on the rate constant and the concentration of the reactant and so is expressed as t1/2=1k[A]0. A certain first-order reaction (A→products A → p r o d u c t s ) has a rate constant of 9.30×10−3...
There are two molecules with the formula C3H6. Propene (H2C=CH-CH3)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 propene with a rate constant of 3.57 × 10–2 min–1. The reaction is first order with respect to cyclopropane concentration. What fraction of the cyclopropane remains after 45 min at 499.5 °C? Please write down the steps Thank you
