The rate constant for a particular reaction that is 1st-order in N2O5 is 0.525 min–1. How much time will it take for the concentration of N2O5 to decrease to one-third its initial concentration? Make sure you pick an answer with the correct units.
(Hint: Fora 1st-order reaction, the amount of time it takes to reduce a reactant's concentration to one-third is independent of the initial concentration of reactant.)

+ Half-life for First and Second Order Reactions 11 of 11 The half-life of a reaction, t1/2, is the time it takes for the reactant concentration A to decrease by half. For example, after one half-Me the concentration falls from the initial concentration (Alo to A\o/2, after a second half-life to Alo/4 after a third half-life to A./8, and so on. on Review Constants Periodic Table 11/25 For a second-order reaction, the half-life depends on the rate constant and the...
