For a first-order reaction, the half-life is constant. It depends only on the rate constant k and not on the reactant concentration. It is expressed as t1/2=0.693kt1/2=0.693k 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 Part A. A certain first-order reaction (A→products) has a rate constant of 3.00×10−3 s−1 at 45 ∘C∘C. How many minutes does it take for the concentration of the reactant, [A],...
