- B Hydrolysis of aqueous sucrose solution in the presence of aqueous mineral acid
- C \(2 \mathrm{H}_2 \mathrm{O}_2(\mathrm{l}) \stackrel{\mathrm{Pt}(\mathrm{s})}{\longrightarrow} 2 \mathrm{H}_2 \mathrm{O}(l)+\mathrm{O}_2(\mathrm{~g})\)
- D Hydrolysis of liquid in the presence of aqueous mineral acid
Answer & Solution
Correct Answer
(C) \(2 \mathrm{H}_2 \mathrm{O}_2(\mathrm{l}) \stackrel{\mathrm{Pt}(\mathrm{s})}{\longrightarrow} 2 \mathrm{H}_2 \mathrm{O}(l)+\mathrm{O}_2(\mathrm{~g})\)
Step-by-step Solution
Detailed explanation
\(2 \mathrm{H}_2 \mathrm{O}_2(l) \stackrel{\mathrm{Pt}(\mathrm{s})}{\longrightarrow} 2 \mathrm{H}_2 \mathrm{O}(l)+\mathrm{O}_2(\mathrm{~g})\) In this reaction, reactant and catalyst are in different phase, hence it is an example of heterogeneous catalysis.
