- Analytical solution of reactor design equation: Consider the irreversible reaction, which occurs in the gas phase, under isothermal and isobaric conditions:
A + B → 2C + D
The applicable rate law (non-elementary) is –rA= kCACB. Assume A is the limiting reactant.
- Write out the full rate law expressionas a function of conversion XA, given FA0= 1 moles/min and FB0= 3 moles/min (inlet molar flow of products is zero). Show this rate expression two times, one with parameters only (no numbers substituted in) and the second with all known or calculated values inserted.
- What is the PFR reactor volumerequired to achieve a conversion of XA= 85% if the influent volumetric flow rate (v0) is 5 L/minute and the reaction rate constant k = 2.2 (L/moles) minutes-1? Develop your solution by performing the analytical integration of the differential equation, using integration tables in Appendix A of the textbook. Credit will not be given for part (b) of this problem unless the solution is shown analytically.

- do not type the answersarrow_forwardCould it please be hand writtenarrow_forwardYou are carrying out a reaction in the laboratory. You need to convert 1.00 mole of reactant X into products. This reaction shows first-order kinetics, and the reaction mixture has a constant volume of 1.00 L. At 1:00pm, you start the reaction at 25\deg C with 1.00 mole of reactant X. At 2:00pm, you find that 0.70 moles of reactant X remain. You immediately increase the temperature of the reaction mixture to 35\deg C. At 3:00pm, you discover that 0.25 moles of reactant X are still present. You want to be able to finish the reaction by 4:00pm, but you cannot stop the reaction until only 0.01 moles of reactant X remain. You must increase the temperature again. What is the minimum temperature required to complete the reaction by 4:00pm? (Remember, the reaction is complete when only 0.01 moles of X remain.)arrow_forward
