A catalyst for automobile exhausts removes carbon dioxide. True or False?
that is true
What element are catalytic converters in an automobile made of?
Catalytic converters are made of platinum-iridium catalyst or a ceramic monolith
What catalyst is common in automobile exhaust?
The common catalyst in automobile exhaust is a catalytic converter, which contains precious metals like platinum, palladium, and rhodium. This device helps to convert harmful pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances like carbon dioxide, nitrogen, and water vapor through a chemical reaction.
Why were cars considered the most important catalyst for social change in the 1920's?
The automobile was arguably the most important catalyst for social change in the 1920's, liberating Americans from often restrictive home or neighborhood situations. Many women used the cars to save time in their daily domestic chores.
Why a catalyst is not considered a reactant or product in chemical reaction?
A catalyst is unchanged by the reaction, and remains as it was. It causes the start of the reaction, but is still there AFTER the reaction. Example- the catalytic converter on an automobile exhaust contains platinum metal. This causes a chemical reaction to take place in the exhaust gasses, but the metal remains in the converter, and is not consumed.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
Which does a catalyst not change?
Catalyst is not a reactant.
Catalyst vs one without catalyst What is different?
what is the purpose of catalyst in textile paint?
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.
Is copper a catalyst?
yeap, a heat catalyst
What is the main difference between a heterogeneous catalyst and a homogeneous catalyst?
The heterogeneous catalyst is not mixed with the reactants.
