Areactor with a number of dividing baffles is to be used to run the reaction a 4 r with -ra 0.05 ca mol/liter. min a pulse tracer test gives the following output curve: time, min 0 10 20 30 40 50 60 70 concentration reading 1 35 38 40 40 39 37 36 35 (a) find the area under the c versus t curve. (h) find the e versus t curve. (c) calculate the variance of the e curve. (d) how many tanks in series is this vessel equivalent to? (e) calculate xa assuming plug flow. (1) calculate xa assuming mixed flow. (g) calculate xa assuming the tanks-in-series model. (h) calculate xa directly from the data.
