Which of the following is an example for heterogeneous catalysis reaction?
Options
- A2 SO ₂(g)+ O ₂(g) NO (g) 2 SO ₃(g)
- BHydrolysis of aqueous sucrose solution in the presence of aqueous mineral acid
- C2 H ₂ O ₂( l ) Pt ( s ) 2 H ₂ O (l)+ O ₂( ~g )
- DHydrolysis of liquid in the presence of aqueous mineral acid
Correct answer
C. 2 H ₂ O ₂( l ) Pt ( s ) 2 H ₂ O (l)+ O ₂( ~g )
Step-by-step solution
2 H ₂ O ₂(l) Pt ( s ) 2 H ₂ O (l)+ O ₂( ~g ) In this reaction, reactant and catalyst are in different phase, hence it is an example of heterogeneous catalysis.
