Options

A. `2Cu_(2)S+5O_(2) to 2CuSO_(4)+2CuO`
B. `2Cu_(2)S+3O_(2) to 2Cu_(2)O+2SO_(2) uarr`
C. `2CuFeS_(2)+O_(2) to Cu_(2)S+2FeS+SO_(2)`
D. `FeO+SiO_(2) to FeSiO_(3)`

Answer

To determine which reaction does not occur in Bessemer's converter, we need to analyze the reactions that typically take place during the extraction of copper in this process.

### Step-by-Step Solution:

1. **Understanding Bessemer's Converter**:
- Bessemer's converter is primarily used for the extraction of copper from its sulfide ores. The main reactions involve the oxidation of copper(I) sulfide (Cu2S) to produce copper metal and sulfur dioxide (SO2).

2. **Identifying the Reactions**:
- The reactions that occur in Bessemer's converter include:
- **Reaction 1**: \(2 Cu_2S + 3 O_2 \rightarrow 2 CuO + 2 SO_2\)
- **Reaction 2**: \(Cu_2S + 2 Cu_2O \rightarrow 6 Cu + SO_2\)
- **Reaction 3**: \(2 Cu_2S + 5 CO_2 \rightarrow 2 CuSO_4 + 2 CuO\)
- **Reaction 4**: \(2 Cu_2S + Cu_2SO_4 \rightarrow 4 Cu + 2 SO_2\)
- **Reaction 5**: \(FeO + SiO_2 \rightarrow FeSiO_3\)

3. **Analyzing the Given Reaction**:
- The reaction in question is:
- \(2 CuFeSO_2 \rightarrow SO_2 + O_2 \rightarrow Cu_2S + 2 FeS + SO_2\)
- This reaction involves the conversion of copper iron sulfide (CuFeSO2) into copper(I) sulfide (Cu2S) and iron sulfide (FeS), which is not a typical reaction that occurs in Bessemer's converter.

4. **Conclusion**:
- Since the reaction \(2 CuFeSO_2 \rightarrow SO_2 + O_2 \rightarrow Cu_2S + 2 FeS + SO_2\) does not represent the oxidation of Cu2S or the production of copper metal from Cu2S, it is concluded that this reaction does not occur in Bessemer's converter.

### Final Answer:
The reaction that does not occur in Bessemer's converter is:
\[ 2 CuFeSO_2 \rightarrow SO_2 + O_2 \rightarrow Cu_2S + 2 FeS + SO_2 \]
