Select one of the following statements that is FALSE about CSTRs and PFRs:

The CSTR operates at a reaction rate in its volume that is equal than its outlet reaction rate.

The CSTR operates at a reaction rate in its outlet that is equal to the minimum reaction rate of the PFR that exists at the PFR’s inlet.

The PFR cannot operate at only one reaction rate due to having non-zero axial dispersion in the flow of material.

The PFR operates at its outlet a minimum reaction rate that is equal to the reaction rate of the CSTR at its outlet.

Answer #1

answer :  The CSTR operates at a reaction rate in its outlet that is equal to the minimum reaction rate  of the PFR that exists at the PFR’s inlet.

Below two figure said that at the inlet of PFR    is minimum. so the rate at inlet of PFR is maximum.

so above statement is false which said that minimum reaction rate  of the PFR that exists at the PFR’s inlet.

Indicate whether each of the following statements is true or false. The sole reason that an overhead volume variance exists in full absorption costing is because fixed overhead costs are being absorbed. Variable costing provides more useful information for make-or-buy decisions than does full-absorption costing. Overhead volume variances occur frequently in manufacturing environments but seldom in service environments, where full-absorption costing is used. The contribution margin is defined as the difference between revenue and variable manufacturing costs. An argument against...
