For first-order reaction the half-life period t12. T_12 dfracln 2k approx dfrac0693k label5 The formula for t 1 2 shows that for first order reactions the half-life depends solely on the reaction rate constant k. Relationship Between Half-life and Zero-order Reactions.
So lets get some space over here.
Present your answer to 2 significant figures. The formula for half-life in chemistry depends on the order of the reaction. Therefore A2 k 0 t ½. T 12 0693k.
