A ferrum that is trapped in the cells of a mononuclear phagocyte system either quickly returns to circulation (a half-life of 34 minutes) or is postponed to a stock (half-life of 7 days). The processes follow the first-order equation at 310K. Calculate the rate constants of both processes at a given temperature and bring their values to the same units. Calculate how much ferment (in% of baseline) will return to circulation in 5 days at this temperature?
