What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What does a catalyst do in a chemical reaction?
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
What is it called when you slow down a chemical reaction?
This is called an inhibitor or negative catalyst
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 chemical speeds up a reation but doesnt react itself?
Such chemicals are called as catalysts. Example:- Nickel metal is widely used as a catalyst.
What is a chemical which speeds a reaction called?
catalyst
What is the substances that speed up chemical reactions?
An enzyme/catalyst
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
A substance that accelerate the rate of a chemical reaction is called what?
It is called a catalyst.
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.
