1. A CSTR polymerization reactor follows a first order reaction, A + B The following data are given. CPA=175 J/K-mol Cra=98 J/K-mol Inlet temperature, T, = 250K Equimolar Inlet molar flow rate-120 mol/h Coolant Temperature, T, = 320K Volumetric flow rate: 6.5 m³/h AH-72,000 J/mol uA 1.0 x 10 J/h-K VCSTR= 28 m³ Asked: a) Express X₁ as a function of reactor temperature, T. (15 pts) (Hint: Start with an Energy balance of the reaction) b) Express X₁ as a function of residence time, t. (15 pts) (Hint: Start with a material balance of the reaction) c) What if rx-kp C (fka /k)¹/², What is the new expression of conversion, X, in terms of residence time, t? (10 pts) d) In connection to letter e, what is the required initiator concentration, , given that Kp = 4.95 s¹, (ka/k)¹/2 = 1.0 x 10³ and initiator efficiency, f=0.8. (10 pts) ►C; TA= KCA
