A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:
What else can I help you with?
What best explains the role of a catalyst in a chemical reaction?
A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does this by providing an alternative reaction pathway with a lower energy barrier. The catalyst itself is not consumed in the reaction and can be reused multiple times.
Is sulphuric acid a positive catalyst?
Sulphuric acid is not a positive catalyst. It is a strong mineral acid that can act as a catalyst in certain chemical reactions, but its role as a catalyst is not specific to promoting the forward reaction.
What is role of sulphuric acid in dehydration of ethanol?
Acts as the dehydrating agent (catalyst).
What is biologic catalyst that is protein in nature?
well a catalyst is something that speeds up a reaction so an enzyme no?
What is the role of a manganese in a reaction?
See for the biological role at: http://en.wikipedia.org/wiki/Manganese.
How can an enzyme be a catalyst?
An enzyme has the role of a catalyst but in biochemistry.
When hydrogen burns what is oxygenated role?
Oxygen acts as a reactant.
What role does a catalyst play in science?
A catalyst reduces the energy needed to start a chemical reaction.
What role does benzene ring play in bonding?

What is the role of decomposition catalyst in the breakdown of hydrogen peroxide?
The decomposition catalyst helps speed up the breakdown of hydrogen peroxide into water and oxygen by providing an alternative pathway for the reaction to occur. This catalyst lowers the activation energy required for the reaction to take place, making it happen more quickly.
What is the role of a hydrogen peroxide decomposition catalyst in accelerating the breakdown of hydrogen peroxide into water and oxygen?
A hydrogen peroxide decomposition catalyst speeds up the reaction that breaks down hydrogen peroxide into water and oxygen. This catalyst lowers the activation energy needed for the reaction to occur, making it happen faster.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
