The correct Answer is:
To solve the question, we need to match the reactions in Column 1 with the corresponding processes in Column 2 and the ores in Column 3. Let's analyze each reaction and determine the correct matches step by step. ### Step-by-Step Solution: 1. **Identify the Reactions**: - (I) PbS → PbO - (II) CaCO₃ → CaO - (III) ZnS → Zn - (IV) CuFeS₂ → Cu 2. **Identify the Processes**: - (i) Roasting - (ii) Calcination - (iii) Carbon reduction - (iv) Self reduction 3. **Identify the Ores**: - (P) Zinc blende (ZnS) - (Q) Galena (PbS) - (R) Pyrite (CuFeS₂) - (S) Limestone (CaCO₃) 4. **Match the Reactions with Processes and Ores**: - **For Reaction (I) PbS → PbO**: - This is a roasting process (sulfide ore to oxide). - Match: (I) with (i) Roasting and (Q) Galena. - **For Reaction (II) CaCO₃ → CaO**: - This is a calcination process (carbonate ore to oxide). - Match: (II) with (ii) Calcination and (S) Limestone. - **For Reaction (III) ZnS → Zn**: - This is a roasting process (sulfide ore to metal). - Match: (III) with (i) Roasting and (P) Zinc blende. - **For Reaction (IV) CuFeS₂ → Cu**: - This is a self-reduction process (sulfide ore to metal). - Match: (IV) with (iv) Self reduction and (R) Pyrite. 5. **Summarize the Matches**: - (I) PbS → PbO → (i) Roasting → (Q) Galena - (II) CaCO₃ → CaO → (ii) Calcination → (S) Limestone - (III) ZnS → Zn → (i) Roasting → (P) Zinc blende - (IV) CuFeS₂ → Cu → (iv) Self reduction → (R) Pyrite 6. **Identify Incorrect Matches**: - From the analysis, we can see that: - (I) is correctly matched. - (II) is correctly matched. - (III) is incorrectly matched with (ii) Calcination instead of (i) Roasting. - (IV) is correctly matched. ### Conclusion: The incorrect options based on the matches are: - (III) ZnS → Zn should match with Roasting, not Calcination.
