The elementary gas-phase reaction (ch3)3cooh(ch3)3 → c2h6 + 2ch3cochz is carried out isothermally in a flow reactor with no pressure drop. the specific reaction rate at 50 °c is 104 min' and the activation energy is 85 kj/mol. pure di- tert-butyl peroxide enetrs the reactor at 10 atm and 127 °c and a molar flow rate of 2.5 mol/min. calculate the reactor volume and space time to achieve 90% conversion in: a. a pfr (ans. 967 dm3) b. a cstr (ans. 4700 dm) c. pressure drop. plot x, y, as a function of the pfr colume when a = 0.001 dm-3. what are x and y at v = 500 dm3?
