Reactant A decomposes with stoichiometry A→R and with rate dependent only on C_A. The following data on this aqueous decomposition are obtained in a mixed flow reactor:

Determine which setup, plug flow, mixed flow, or any two- combination gives minimum τ for 90% conversion of a feed consisting of C_A0 = 100. Also find this τ minimum. If a two-reactor scheme is found to be optimum, give C_A between stages and τ  for each stage.
