Webb3 dec. 2024 · the simplest example of this type of reaction is between ethene and hydrogen in the presence of a nickel catalyst. CH 2 = CH 2 + H 2 Ni as catalyst CH 3 CH 3. In actual, this is a useless reaction, because you are converting the very useful ethene into the relatively useless ethane. However, the same reaction will occur with any compound that ... Webb15 aug. 2024 · In a heterogeneous reaction, the catalyst is in a different phase from the reactants. In a homogeneous reaction, the catalyst is in the same phase as the reactants. What is a phase? If you look at a mixture and can see a boundary between two of the components, those substances are in different phases.
