Item 9 9 of 18 (> I Review Constants | Periodic Table The half-life of a reaction, t2, is the time it takes for the reactant concentration [A] to decrease by half. For example, after one half-life the concentration falls from the initial concentration [A]o to [A]o/2, after a second half-life to [Alo/4, after a third half-life to [A]o/8, and so on. on. For a first-order reaction, the half-life is constant. It depends only on the rate constant k and nof on the reactant concentration. It is expressed as t1/2 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 EA. Part A A certain first-order reaction (A→products) has a rate constant of 5.70x10-s at 45 °C. How many minutes does it take for the concentration of the reactant, [A], to drop to 6.25% of the original concentration?
