I need the answer as soon as possible

1) The volumetric flow rate through a reactor is 10 dm/min. A pulse test gave the following concentration measurements at the outlet: 1 (min) c X 105 1 (min) CX 10 238 136 0 0.4 1.0 2 3 4 5 6 8 10 0 329 622 812 831 785 720 650 523 418 15 20 25 30 35 40 45 50 60 77 44 25 14 8 5 1 a) Plot the external age distribution E(t) as a function of time. b) Plot the external age cumulative distribution F(t) as a function of time. c) What are the mean residence time tm and the variance, o?? d) What fraction of the material spends between 2 and 4 min in the reactor? e) What fraction of the material spends longer than 6 min in the reactor? 1) What fraction of the material spends less than 3 min in the reactor? g) Plot the normalized distributions E(O) and F(O) as a function of O. h) What is the reactor volume
