Question

Use the atomic species balance for this chemical reaction.  Do not use the extent of reaction or molecular species balances. 

## Propylene Ammoxidation Process

**Chemical Reaction:**
\[ \text{C}_3\text{H}_6 + \text{NH}_3 + \frac{3}{2} \text{O}_2 \rightarrow \text{C}_3\text{H}_3\text{N} + 3 \text{H}_2\text{O} \]

**Problem Statement:**
The feed to the propylene ammoxidation process contains 10.0% mole propylene, 12.0% ammonia, and 78.0% air. A fractional conversion of 30.0% of the limiting reactant is achieved. Taking 100 mol of feed as a basis, determine:
- The limiting reactant
- The molar amounts of all gas constituents for a 30% conversion of the limiting reactant

**Approach:**
- Determine the molar amounts in atomic species balance and molecular species balances.

**Diagram Explanation:**

- **Reactor Setup:**
  - **Input (Feed Basis):**
    - 100 mol of feed
    - 10.0 mol C₃H₆/mol air
    - 12.0 mol NH₃/mol air
    - 78.0 mol O₂/mol air
  
- **Output:**
  - Molar flow rates:
    - \( n_{\text{C}_3\text{H}_6} \)
    - \( n_{\text{NH}_3} \)
    - \( n_{\text{O}_2} \)
    - \( n_{\text{C}_3\text{H}_3\text{N}} \)
    - \( n_{\text{H}_2\text{O}} \)

**Calculations:**

**Answers:**
- \( n_{\text{C}_3\text{H}_6} = 7.0 \text{ mol} \)
- \( n_{\text{NH}_3} = 9.0 \text{ mol} \)
- \( n_{\text{O}_2} = 11.6 \text{ mol} \)
- Unreacted flows to other species calculated
- Extent of reaction values at 30% conversion
- \( n_{\text{C}_3\text{H}_3\text{N}} = 3.0 \text{ mol} \)
