Reference no: EM13144152

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 second-order reaction (B -> products) has a rate constant of 1.15×10?3 at 27 and an initial half-life of 260 . What is the concentration of the reactant B after one half-life?
