Half-life equation for first-order reactions: t1/2= 0.693/kwhere t1/2 is the half-life in seconds (s), and k is the rate constant in inverse seconds (s^-1). A certain first-order reaction has a rate constant f 7.30x10^-3s^-1. How long will it take for the reactant to drop 1/8 of its initial value? Express your answer with the appropriate units.
