a. A reaction is observed to proceed with a rate constant of 1000s-1at 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? b. 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 twodoses 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? c. Determine the pH and the pOH of a solution made by mixing 1.00 ml of concentrated hydrochloric acid (12.0 M) with water to make a final volume of 100.0 ml?
