A) The exothermic reversible reaction \( A \leftrightarrow B \) is first order in each direction. Rate constants, and hence equilibrium constants, are temperature dependent. The table provides relevant values at two temperatures. \( \mathrm{C}_{\mathrm{A} 0}=6.0 \mathrm{~mol} / \mathrm{L} \). A.1) Find the equilibrium fractional conversion at each temperature. A.2) Find the space time required for an isothermal CSTR to reach a fractional conversion of \( 0.80 \) at each temperature. A.3) Compare and contrast the advantages and disadvantages of operating the CSTR at each temperature. A.4) You have two CSTRs available, each with a volume of \( 5000 \mathrm{~L} \). The reactors must be operated at either 60 or \( 90^{\circ} \mathrm{C} \) and can be arranged in series or in parallel. Suggest the most efficient way to operate them to achieve a fractional conversion of \( 0.93 \) and why this is the best choice. A.5) For the arrangement you selected in A.4, calculate the highest volumetric flow rate for the feed that can be used while still maintaining a fractional conversion of at least \( 0.93 \).
