I Review | Constants | Periodic Table
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-life the
concentration falls from the initial concentration
Ao to [Alo/2, after a second half-life to [A]o/4,
after a third half-life to [Alo/8, and so on. on.
v Correct
Part B
A certain second-order reaction (B→products) has a rate constant of 1.80x10-3 M.s-1 at 27°C and an
initial half-life of 246 s. What is the concentration of the reactant B after one half-life?
Express your answer with the appropriate units.
