Which of the following is not an example of heterogeneous catalysis reaction?

Options

  1. ACombustion of Coal
  2. BHydrogenation of Vegetable oils
  3. COstwald's process
  4. DHaber's process

Correct answer

A. Combustion of Coal

Step-by-step solution

A Since Combustion of Coal is a fast and spontaneous process, no catalyst is required. B Catalyst used in Hydrogenation of Vegetable oils is Ni ( s ) C Catalyst used in Haber's process is Fe ( s ) . D Catalyst used in Ostwald's process is Pt ( s )
