Question
A reaction is observed to proceed with a rate constant of 1000s -1 at 50 ̊C. At 70 ̊C the
reaction is found to have a rate constant of 4000s -1 . Assuming that A is temperature-
independent, what is the activation barrier for this reaction?
2. Most of the medications that we ingest are removed from our bodies via a first order
process. It is the aim of the physician to keep the concentration of medication (in our
body) more or less constant over the treatment period. If a 10% variation in
concentration is the largest acceptable swing, and if the patient is required to take two
doses of the medication per day (i.e. once every 12 hours), what is the largest acceptable
rate constant for the disappearance of the medication and what is the associated half-
life?
