catalysts which are in the same phase to that of reactants and products
Examples: fine iron powder, vanadium(V) oxide
catalytic converter
Homogeneous
Because palladium is a solid metal and the reactants are liquids or gases.
A catalyst is a substance that helps a chemical reaction happen faster without suffering any change. An example sentence is: Because of the catalyst, the project ending early.
Catalysts are compounds that change the speed of chemical reactions. An enzyme is a protein and also a catalyst. So an enzyme can be a catalyst, but a catalyst can't be an enzyme.
NO.. it is not ..it is an alloy.
Heterogeneous means that something is not consistent throughout. Sand is an excellent example of something that is considered to be heterogeneous.
The heterogeneous catalyst is not mixed with the reactants.
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
heterogeneous and homogeneous are words used to describe a system, not a single element. For example, with regards to catalysis you could have a homogeneous catalyst which means one that works in the same phase as the reactant (i.e. both solid or both liquid or both gas) or a heterogeneous catalyst, which works in a different phase to the reactant, so a solid catalyst for a gaseous reactant etc.
For example the ammonia production; the magnetite catalyst is the most common.
Because palladium is a solid metal and the reactants are liquids or gases.
A heterogeneous mixture is composed of two or more components that are not evenly distributed and are easily observable. An example of a heterogeneous mixture is beef stew.
milk
milk
An example would be a mixture of flour and water. Heterogeneous mixtures have two different phases.
a heterogeneous mixture.
A catalyst is a substance that helps a chemical reaction happen faster without suffering any change. An example sentence is: Because of the catalyst, the project ending early.
This compound is an active homogeneous epoxidation catalyst in its own right.
