Platinum and rhodium are commonly used jointly in catalytic converters. A platinum-rhodium catalyst is a reduction catalyst, which is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the nitrogen oxides (NO and NO2, together called NOx) emissions.
When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2.
For example:
2NO => N2 + O2 or 2NO2 => N2 + 2O2

What is the substance of a chemical reaction that accelerates?
A substance that accelerates a chemical reaction is called a catalyst. Catalysts work by lowering the activation energy needed for a reaction to occur, which speeds up the reaction without being consumed in the process.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
Is copper a catalyst?
yeap, a heat catalyst
Catalyst at work in the body?
An example of a catalyst in the body is enzymes, which help speed up chemical reactions without being consumed in the process. Enzymes are involved in various processes in the body such as metabolism, digestion, and cellular signaling. They lower the energy required for reactions to occur, making them essential for the proper functioning of biological systems.
What do you call a substance that accelerates the rate of a chemica reaction?
A substance that accelerates the rate of a chemical reaction is called a catalyst.
Why do catalyst work without adding heat?
A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.
What is the job of catalyst?
Catalysts work by lowering the "start-up" energy of a reaction.
What is the substance of a chemical reaction that accelerates?
A substance that accelerates a chemical reaction is called a catalyst. Catalysts work by lowering the activation energy needed for a reaction to occur, which speeds up the reaction without being consumed in the process.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?

Which does a catalyst not change?
Catalyst is not a reactant.
Are enzyme's catalysts?
Catalyst work in non living things while enzyme work inside living things. They are not catalyst but instead they can be called biocatalysts. Hope it helps.
Is baking soda a catalyst?
As far as I'm aware, the work "catalyst" only applies to things which work on enzymes. Baking powder is a mixture of an acid and an alkali, which reacts upon adding a liquid by releasing Co2. (Although some also react upon heating). It is a chemical reaction, not an enzymatic one, therefore I don't think you can consider it to be a catalyst.
Catalyst vs one without catalyst What is different?
what is the purpose of catalyst in textile paint?
What scientist showed that RNA could act as its own catalyst?
Thomas R. Cech showed that RNA could act as its own catalyst. His work changed scientific opinion that all enzymes were proteins.
What is a substance that speeds up a chemical process?
catalyst-by lowering activation energy
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
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.
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
