A catalyst is a substance that accelerates or increases the rate of a chemical reaction. In principle a catalyst should remain unaffected during the process. However normally it loses some activity during it resuses.

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.
Define the literary term catalyst?
A catlyst is someone (or an event) that causes change.
Define five ways you can speed up or slow down a reaction?
Changing the temperature of the reaction can speed it up by increasing molecular collisions and kinetic energy. Adding a catalyst can speed up a reaction by lowering the activation energy required for the reaction to proceed. Increasing the concentration of reactants can speed up a reaction by providing more reactant molecules to collide and react. Changing the surface area of solid reactants can speed up a reaction by exposing more reactant surface area for collisions to occur. Adjusting the pH of the reaction environment can speed up or slow down a reaction by affecting the ionization state of reactants and the reaction rate.

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 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 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.
