Problem 8-9 (Level 1) The liquid phase reaction AR is taking place in an ideal batch reactor. The reaction is homogeneous and irreversible, and the rate equation for the disappearance of A is rA=kCA2 At 150C, the value of k is 7.601/molh. The enthalpy change on reaction, HR, is 37.5kcal/molA at 150C. The initial concentration of A is 0.65mol/l. 1. If the reactor is operated isothermally at 150C, how much time is required to achieve a fractional conversion of A, xA=0.95? 2. If the reactor is operated isothermally at 150C, what percentage of the total heat will be transferred in the first quarter of the total time, i.e., of the time you calculated in Part 1? The second quarter? The third quarter? The last quarter? 3. The reactor is to be kept isothermal at 150C over the whole course of the reaction. Cooling water is available at 30C at a flow rate of 6000kg/h. If the reactor volume is 10001 and the overall heat-rransfer coefficient is 500kcal/m2 hC, how much heat-transfer area must be installed in the reactor? 4. If the reactor is operated adiabatically and the initial temperature is 150C, will the time required to achieve xA=0.95 be greater, the same, or less than what you calculated in Part 1 ?
