a. Give a mathematical expression for the half-life of a first order reaction and of a second order reaction. b. Considering the four factors that determine the rate of a reaction, and “collision theory", explain why you think the half-life of a first order reaction is not dependent on the initial concentration of the reactant, but the half-life of a second order reaction is dependent on the initial concentration of the reactants.

As with any drug, aspirin (acetylsalicylic acid) must remain in the bloodstream long enough to be effective. Assume that the removal of aspirin from the bloodstream into the urine is a lirst-order reaction, with a half-life of about 3 hours. The instructions on an aspirin bottle say to take 1 or 2 tablets every 4 hours. If a person takes 2 aspirin tablets, how much aspirin remains in the bloodstream when it is time for the second dose? (A standard tablet contains 325 mg of aspirin.)
