Q3a: The experimental data in Table 2 shows the concentration of reactant A in time. Time t [s] Concentration CA mol L-') 10 0 20 8 40 6 60 5 120 3 180 2 300 1 Table 2: Evolution of the concentration of reactant A in time. It is suggested that the reaction rate can be expressed as dCA - KCA dt where k is the rate constant and n is the order of reaction. Note: 0.001
