I need the answer as soon as possible

4) A pulse input to a vessel gives the results shown below 0.05 M= 1 mol at 1 = 0 v = 4 liters/min Cpulse, mol/liter V = ? 0 5 1, min (a) Check the material balance with the tracer curve to see whether the results are consistent (b) If the result is consistent, determine tm (mean residence time), V and sketch the E curve. (6) (5) The following E(t) curves were obtained from a tracer test on a tubular reactor. The E(t) expressions are given for the Et) -ift
