What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
Is MnO a catalyst?
Yes, it is a chemical catalyst.
Is copper a catalyst?
yeap, a heat catalyst
How is a catalyst like platinum different from an enzyme?
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.
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.
Give two essential features of a catalyst?
- it speeds up the reaction by offering an alternative root. - it remains the same at the end of the reaction.
Why are enzymes known as bio-catalyst?
Enzymes moderate chemical changes within an organism, and are usually essential to making metabolic functions occur at the proper rates.

What is a substance that speeds up a reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction.
A substance that speeds up rate of a chemical reaction?
Catalyst, biocatalyst or enzyme.
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.
Is MnO a catalyst?
Yes, it is a chemical catalyst.
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.
