Questions 6. A simple case of a series reaction is illustrated below: A, 17A, A , 3 = Assuming an approach of first-order rate equation of the following type: r = k1Cali r2 = k2CA2. The initial concentrations of the three components are: Ci = 1; Cz = CA3 = 0. Write the mass balance equations of each component and solve the equations. Draw the graph of concentrations A1, A2, A3 versus time. = - 12
