Rate = k[A][B] Rate = k[A]^2 Rate = k[B]^2 Rate = k[B][A]^2 %3D Rate = k[A][B]^2 Submit ш

(2) The reaction-rate data given below were obtained using a batch reaction system for the reaction A→products. Plot the data in appropriate form to test the fit for zero- and first-order kinetics. From the plot that gives the best fit, determine the appropriate reaction rate constant (remember the units). Time, min CA, (g/m3) 0 30 0.5 25.4 1 21.6 2 16.9 4 13.1 8 8.3 16 3.2 32 0.31
