When chemists are performing kinetics experiments, the general rule of thumb is to allow the reaction to proceed for 4 half-lives.
(a) Explain how you would be able to tell that the reaction has proceeded for 4 half-lives.
(b) Let us suppose a reaction A → B takes 6 days to proceed for 4 half-lives and is first order in A. However, when your lab partner performs this reaction for the first time, he does not realize how long it takes, and he stops taking kinetic data, monitoring the loss of A, after only 2 hours. Your lab partner concludes the reaction is zero order in A based on the data. Sketch a graph of [A] versus time to convince your lab partner the two of you need to be in the lab for a few days to obtain the proper rate law for the reaction?
