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.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
