The reaction, aA products, is a first order reaction with a rate constant of 1.248 x 10-4 s-1 . a. How long (in seconds) does it take for the initial amount of A to decrease by 30%? b. What fraction of reactant remains after 30 minutes? c. What is the half-life for the reaction? d. How long does it take for the initial amount of reactant to decrease by 87.5%?
+ 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...
