A series of beakers are set up containing a chemical compound that decays over time. At time intervals, the concentration in one of the beakers is measured and recorded between times (t) (h) and concentrations (C) (mg/L). The model for the data is expressed as dc dt where k is the reaction rate (h-¹) and n is the order of reaction. Table 2 shows the value of concentration, C (mg/L) vs time, t (h).
