In a first-order reaction. let's suppose that a quantity, x, of
reactant is added at regular intervals of time, [delta t]. at first
the amount of reactant in the system builds up; eventually, however,
it levels off at a "saturation vlaue" given bythe expression:
saturation value = x/1-10(negative a) , where a = 0.30
deltat/half life.
this analysis applies to prescription drugs, where you take
acertain amount each day. suppose you take 0.100 g of a drugthree
times a day and that the half-life for elimination is 2.0days. (a)
using this equation, calculate the mass of the frugin the body at
saturation (the saturation value). (b) suppose further that side
effects show up when 0.500 g of the drugaccumulates in the body. as
a health-care professional, whatis the maximum dosage you could
assign to a patient for an 8-hourperiod without the
side-effects?
