In addition, a model reaction with two reactants such as (8) has a TOF of (9) which on saturation of R 1 or R 2 will have a TOF of (10) respectively. It is clear from eq 10 that it is not possible to have saturation for both reactants in this model reaction.

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. WebbCatalysts are highly specific compounds. They have an ability to direct the reaction to yield a particular product. The reaction with same reactants but different catalyst may yield different products. This is termed as the … WebbCatalysis is the process of adding a catalyst to facilitate a reaction. During a chemical reaction, the bonds between the atoms in molecules are broken, rearranged, and rebuilt, recombining the atoms into new molecules. Catalysts make this process more efficient by lowering the activation energy, which is the energy barrier that must be ... slumberland service claim
