- Question 3 (5pt): A chemical reaction. In an elementary chemical reaction, single molecules of two reactants A and B form a molecule of the product C : ABC. The law of mass action states that the rate of reaction is proportional to the product of the concentrations of A and B: d[C] dt = k[A][B] (where k is a constant positive number). Thus, if the initial concentrations are [A] = = a moles/L and [B] = b moles/L we write x = [C], then we have (E): dx dt = k(ax)(b-x) 1 (a) Write the differential equation (E) with separate variables, i.e. of the form f(x)dx = g(t)dt.
