The following pattern in a reactor is evaluated by determining the residence time distribution function $(E).$ Below are the results obtained for tracer concentration in the effluent after introducing tracer with a $0\mathrm{.}06M$ concentration.

$\backslash$table$[[$Time $(min),$Concentration $($M$)],[1,0\mathrm{.}002],[3,0\mathrm{.}011],[5,0\mathrm{.}016],[10,0\mathrm{.}024],[15,0\mathrm{.}034],[20,0\mathrm{.}040],[25,0\mathrm{.}046],[30,0\mathrm{.}051]]$

a$)$ Is this a pulse or a step experiment? Explain why.

b$)$ Determine the exit age $($E$)$ with plots and tables.

c$)$ By comparing your results with the literature, determine the type of reactor used.

Explain all your procedures, the formulas used, and your conclusions.
