Half-life equation for first-order reactions: t1/2=0.643k where t1/2 is the half-life in seconds (s), and k is the rate constant in inverse seconds (s−1). What is the rate constant of a first-order reaction that takes 337 seconds for the reactant concentration to drop to half of its initial value? Express your answer with the appropriate units.
