Half-life equation for first-order reactions: \it t_{\rm 1/2}\rm = {0.693 \over \it k}~ where \it t\rm _{1/2} is the half-life in seconds \rm (s), and \it k is the rate constant in inverse seconds \rm (s^{-1}). What is the rate constant of a first-order reaction that takes 8.80 minutes for the reactant concentration to drop to half of its initial value? A certain first-order reaction has a rate constant of 7.30×10−3 \rm s^{-1}. How long will it take for the reactant concentration to drop to \rm {1 \over 8} of its initial value? | ||
