What is cataylyst?
A catalyst is something that sparks/causes a reaction. Usually used in reference to a protein being the catalyst for a reaction in biology.
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.
What is a chemical substance that helps control reactions?
A catalyst is generic term used to influence rates of reaction. The catalyst lowers the activation energy required to start the reaction. In biology, catalysts are called enzymes.
What is a chemical used to speed up a reaction called?
In chemistry it's called a catalyst. In biology it's usually a protein and is called an enzyme.
What is a substance that lowers the activation energy for a chemical reaction but is not changed or used up in the reaction?
This is called a catalyst. In biology, it is referred to as an enzyme (biological catalyst). Catalysts can also be used to speed up or slow down chemical reactions.
What is a Catalyst mean in chemistry?
In Biology, a catalyst is a substance which speeds up a chemical reaction, without being changed themselves. Biological catalysts are found in living organisms.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What are proteins that speed up a chemical reaction in living things?
A catalyst. Definition from Pretence Hall Biology: A catalyst is a protein that speeds up the rate of a chemical reaction.
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 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.
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.
