# 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) r_{C} = 2r_{1} + r_{6}

b) r_{C} = r_{1} – r_{2} – r_{4} – r_{6} – r_{7}

c) r_{C} = 2r_{1} –2r_{2} – r_{4} – 2r_{6} – ½r_{7}

d) r_{C} = 2r_{1} –2r_{2} – r_{4} – 3r_{6} – ½r_{7}

e) r_{C} = kC_{C}

f) r_{C} = ½r_{1} – ½r_{2} – r_{4} –1/3r_{6} + 2r_{7}

**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.

JaneteHello 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
