The chemical reaction that involves roasting process is
- A \(\mathrm{Fe}_2 \mathrm{O}_3+3 \mathrm{CO} \longrightarrow 2 \mathrm{Fe}+3 \mathrm{CO}_2\)
- B \(2 \mathrm{Al}+\mathrm{Fe}_2 \mathrm{O}_3 \longrightarrow 2 \mathrm{Fe}+\mathrm{Al}_2 \mathrm{O}_3\)
- C \(2 \mathrm{ZnS}+3 \mathrm{O}_2 \longrightarrow 2 \mathrm{ZnO}+3 \mathrm{SO}_2\)
- D \(\mathrm{FeO}+\mathrm{SiO}_2 \longrightarrow \mathrm{FeSiO}_3\)
Answer & Solution
Correct Answer
(C) \(2 \mathrm{ZnS}+3 \mathrm{O}_2 \longrightarrow 2 \mathrm{ZnO}+3 \mathrm{SO}_2\)
Step-by-step Solution
Detailed explanation
Roasting is the process of heating of sulphide ores in excess of air to convert them into oxides. Thus, reactions, \(2 \mathrm{ZnS}+3 \mathrm{O}_2 \longrightarrow 2 \mathrm{ZnO}+3 \mathrm{SO}_2\) occurs during roasting process.
