Reaction rates are usually expressed as the concentration of reactant consumed or the concentration of product formed per unit time. The units are thus moles per liter per unit time, written as M/s, M/min, or M/h.
[11 where r is the mean division rate in the time interval t~-tx. Indefining it we have considered the increase in cell concentration.When the average size of the cells does not change in the timeinterval considered, the increase in bacterial density is propor-tional to the increase in cell concentration.
