- DHydrogenation of oil
Correct answer
C. Hydrolysis of sucrose in presence of dilute hydrochloric acid
Step-by-step solution
In homogeneous catalysis, reactants and catalyst are in the same phase. (a) SO ₂( ~g )+ O ₂( ~g ) Pt ( s ) SO ₃( ~g ) (Contact process) It is an example of heterogeneous catalysis. (b) N ₂( ~g )+ H ₂( ~g ) Fe ( s ) 2 NH ₃( ~g ) (Haber's process) It is an example of heterogeneous catalysis. (c) C ₁₂ H ₂₂ O ₁₁( aq )+ H ₂ O ( aq ) HCl ( aq ) C ₆ H ₁₂ O ₆+ C ₆ H ₁₂ O ₆ It is an example of homogeneous catalysis. (d) Thus, it is also an example of heterogeneous catalysis.
