A certain unimolecular reaction is zero order. If the half-life of this reaction is 42 seconds, how long will it take for the reaction to be 70% complete? Report your answer to 1 decimal place.
1.) The reaction A (aq)-->B (aq) is a first order reaction where the haf life of A (aq) of the reaction at 25 degrees celsius is 377 seconds. The half life of the reaction at 35 degrees celsius is 333 s. What is the necessary time for the concentration of A (aq) to fall from 0.777 M to 0.222 M at 50 degrees celsius? The answer is 507 seconds? 2.) THe N2O (g) decomposes to give N2 (g) and O2...

+ 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...
