In a first order reaction, the half life is 9 minutes. What is the rate coefficient (in s1)? Express your answer in s1, correct to four decimal places. Please do not include the correct units (s1) in your answer and do not use scientific notation.
+ 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...
