WebIn zero-order reactions, the rate law equation is Rate = k and the unit of rate constant in this case is, mol L − 1 s − 1. For first-order reactions, Rate = k [A]. The constant rate unit, in this case, is s − 1. On the other hand, second-order reactions have a rate law of, Rate = k [A] [B], and rate constant unit of. mol − 1 L s − 1. Webthe rate of reaction as a half-life, t1/2; the time it takes to reduce the concentration of A to half its initial value. At t1/2 for a first order reaction, [A]=[A]o/2, thus: ln[A]o/2=kt1/2 rearranging t1/2 = ln2/k this is also a quick way to determine a rate constant from a plot of product decrease vs time since k = ln2/t1/2 2.50 3.00 3.50 4. ...
