The reaction
2NOBr $\rightarrow$ 2NO + Br 2
exhibits the rate law
Rate = k[NOBr] 2 where k = 1.0 *10 - 5 M - 1 • s - 1 at 25° C. This reaction is run where the initial concentration of NOBr ([NOBr] 0 ) is 1.00 * 10 - 1 M.
-What is one half-life for this experiment?

Quizplus · Accepted Answer

The half-life is the time it takes for the concentration of a reactant to decrease by half. In this experiment, the concentration of the reactant decreases by half every 1.0 x 10^6 s.
