Basic Chemical Engineering Practice Test 4

1. Methane is at the rate 50 moles is supplied to a reactor with air at the rate 1000 moles, the reactor leaves O₂, N₂, CO₂ and H₂O, what is the percentage of O₂ in products?

2. 1 has pure A and 2 has pure B and 3, 4 and 5 has mixture of A and B, how many independent equations are possible?

3. A reactor is supplied with 6 moles of N₂ and 9 moles of H₂, if 3 moles of NH₃ is produced, how many moles of H₂ are left at the end?

4. A reactor is supplied with 2 streams both at the rate 5 mole, one has 40% Cl₂ and 60% N2, and another has pure C₂H₆, if the product has C₂H₅Cl, HCl and N₂ at the rate 20 mole, what is the percentage of HCl in products?

5. If 28 grams of N₂ and 10 grams of H₂ are reacted, how much NH₃ will produce?

6. A reactor is supplied with 5 moles of C₄H₁₀, and it undergoes following reactions C₄H₁₀ + 4H₂O -> 4CO + 9H₂ and C₄H₁₀ + 6.5O₂ -> 4CO₂ + 5H₂O, if 8 moles of CO₂ was produced and 2 moles of C₄H₁₀ remains unreacted, what are the number of moles of CO produced?

7. A reactor is supplied with two steams with equal flow rates, stream-1 containing 75% SO₂, 25% N₂ and stream-2 containing pure H₂S, if the product has 1200 grams of S, and the ratio of H₂S to H₂O is 5 and the ratio of SO₂ to H₂S is 2, what is the rate of streams?

8. A reactor is supplied with 25 moles of C, and it undergoes following reactions C + 0.5O₂ -> CO and C + O₂ -> CO₂, if 13 moles of CO₂ was produced and 5 moles of C remains unreacted, what are the number of moles of CO produced?

9. A reactor is supplied with a feed of composition 46% C₃H₇O₄, 44% O₂ and 10% N₂, if 50% of the limiting reagent is converted into product, what is the percentage of C₃H₇O₄ in the product?

10. A reactor is supplied with glucose and oxygen to produce 40% CO₂, 60% H₂O, what is the ratio of glucose reacted and products?
