catalyst
a catalyst
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.
catalyst-by lowering activation energy
A molecule that speeds up a chemical reaction is called a catalyst. Catalysts work by reducing the activation energy needed for a reaction to occur, which increases the rate of the reaction without being consumed in the process.
A substance that speeds up a chemical reaction is known as a CATALYST.
A substance that speeds the changing of food into a usable form* is called an enzyme. More generally, in any chemical context, a substance that speeds a reaction without itself being changed is called a catalyst._______________________________________*This changing of food into a usable form is called "digestion".
A substance that speeds up a chemical reaction without being consumed is called a catalyst. Catalysts lower the activation energy needed for a reaction to occur, allowing it to proceed faster, but they remain unchanged at the end of the reaction.
This is called a catalyst.
Substances that speed up the rate of reaction are called catalysts. Catalysts participate in chemical reaction but does not get consumed. Yeast is an example of biological catalyst.
An enzyme speeds up a chemical reaction.
