The half-life of a reaction, , is the time it takes for the reactant concentration to decrease by half. For example, after one half-life the concentration falls from the initial concentration to , after a second half-life to , after a third half-life to , and so on. on. A certain first-order reaction () has a rate constant of 6.30×10-3 at 45 . How many minutes does it take for the concentration of the reactant, , to drop to 6.25 of the original concentration?
