Calculate Rate of Formation of Compound in Isothermal PFR Feed

Question

The following set of gas-phase reactions is expected to occur in an isothermal PFR fed a mixture of compounds A and B.

1.    A + B → 2C
2.    2C → A + B
3.    A + B → D
4.    A + C → E
5.    D + E → F + G
6.    3C + F → H + C
7.    G + ½ C → I + J

What is the net rate of formation of C?

a) rC = 2r1 + r6
b) rC = r1 – r2 – r4 – r6 – r7
c) rC = 2r1 –2r2 – r4 – 2r6 – ½r7
d) rC = 2r1 –2r2 – r4 – 3r6 – ½r7
e) rC = kCC
f) rC = ½r1 – ½r2 – r4 –1/3r6 + 2r7

 

Summary

The short answer question belongs to Chemical Engineering and the question is about gas phase reactions expected to occur in isothermal PFR fed into a mixture of two compounds.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
