126. Solving a chemistry problem

The reaction rate constant at 303 K is 3.0*10-5 L*mol-1*s-1. Determine the half-life at the initial concentration C0=0.042 mol/l and the time during which the reagent concentration reaches 0.002 mol/l. In the initial state, the concentrations of the reactants correspond to the stoichiometry of the reaction.
