3. Polystyrene is being produced by solution polymerization of styrene in toluene in a CSTR. Assume that the reactor is an ideal CSTR that operates isothermally at 160C, at steady state, and with no volume changes. Assume an initiator efficiency of 70%. Use the following rate constants: ka - 6.213 s kp - 3286 L/mol's kle = 6.3x10 L/mols The feed stream to the reactor is 2.0 L/s. The concentration of reactants and solvents are as follows: (styrene). - 4.3 mol/L [benzoyl peroxide). -0.0080 mol/L [toluene) - 4.7 mol/L (a) If the reactor volume is 2,000 L, calculate the conversion of styrene. (b) What is the number average degree of polymerization? (c) If AH, is - 70 kJ/mol, calculate the heat load
