![**Ethane Chlorination Process**
Ethane is chlorinated in a continuous reactor through the following reaction:
\[ \text{C}_2\text{H}_6 + \text{Cl}_2 \rightarrow \text{C}_2\text{H}_5\text{Cl} + \text{HCl} \]
Some of the monochloroethane produced undergoes further chlorination in an undesired side reaction:
\[ \text{C}_2\text{H}_5\text{Cl} + \text{Cl}_2 \rightarrow \text{C}_2\text{H}_4\text{Cl}_2 + \text{HCl} \]
### Calculations and Considerations
**a. Degrees of Freedom in the Reactor System**
1. Base the calculation on 100.0 mol of \(\text{C}_2\text{H}_5\text{Cl}\) produced.
2. Assume the feed contains only ethane and chlorine, with complete consumption of chlorine.
3. Determine the degrees of freedom using atomic balances.
**b. Reactor Design Specifications**
1. The reactor achieves an 11.0% conversion of ethane.
2. Selectivity is 10.0 mol \(\text{C}_2\text{H}_5\text{Cl}\) per mol \(\text{C}_2\text{H}_4\text{Cl}_2\).
3. Chlorine presence in the product gas is negligible.
**Calculations Required**
1. Calculate the feed ratio (mol \(\text{Cl}_2\)/mol \(\text{C}_2\text{H}_6\)).
2. Calculate the fractional yield of monochloroethane.
These calculations help in understanding the reactor efficiency and the extent of side reactions, essential for optimizing industrial processes.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fff96cdc2-7807-4421-a794-d30f1f1244f8%2F73b37545-d291-4d07-a143-ad686628c80f%2F6rzhhqa_processed.jpeg&w=3840&q=75)
