(a) Which reactor and what conditions do you recommend? Explain the rea-
son for your choice (e.g. color, cost, space available, weather condi-
tions). Back up your reasoning with the appropriate calculations.
(b) How long would it take to achieve 90% conversion in a 200-dm batch
reactor with Co = Cạo = I M after mixing at a temperature of 77°C?
(c) What would your answer to part (b) be if the reactor were cooled to 0°C?
(Ans. 2.5 days)
