Question

A certain second-order reaction (B>products) has a rate constant of 1.85x10° M.sat 27 °C and an initial half-life of 202 s. What is the concentration of the reactant B after one
half-life?

The half-life of a reaction, t/2. is the time it takes for the reactant
concentration A| to decrease by half. For example, after one half-life the
concentration falls from the initial concentration [Alo to [Alo/2, after a second
half-life to [A]o/4, after a third half-life to [Alo/8. and so on. on.
