Consider the reaction alatex: \longrightarrow ⟶ products. the rate law for this reaction is rate = k[a]2 where k=2.90 latex: \times × 10-2 m-1s-1 at a particular temperature. if the initial [a] = 0.0500 m, what is the value of the half-life?
478 s
34.5 s
690. s

![t_\frac{1}{2}=\frac{1}{k\times [A_0]}](/tpl/images/0496/6747/95401.png)
= half life = time taken for a reaction to complete to half. ![[A_0]](/tpl/images/0496/6747/9a686.png)
