Essentially, the idea of the Malthusian model is the assumption that the rate at which a population of a country grows at a certain time is proportional to the total population of the country at that time. If we assume that the time rate of change of this amount of substance, \(\frac{{dN}}{{dt}}\), is proportional to the amount of substance present, then, \(\frac{{dN}}{{dt}} = kN\), or \(\frac{{dN}}{{dt}} kN = 0\).
