Question

Which of the following is an example of homogeneous catalysis?

• A. Hydrogenation of oil 
• B. Manufacture of ammonia by Haber's process
• C. Manufacture of sulphuric acid by Contact process
• D. Hydrolysis of sucrose in presence of dilute hydrochloric acid

Answer 1

The correct option is D Hydrolysis of sucrose in presence of dilute hydrochloric acid

We have seen from previous videos that the Haber's process is not homogeneous catalysis since Iron catalyst that is used is solid while the rest are gases.
Similary in hydrogenation reaction, reactants are gases while the catalyst is solid as you will be seeing soon.
It is only in the case of D where all the reactants and the catalysts are in the liquid phase.
