catalyst
A substance that speeds up a chemical reaction is known as a CATALYST.
A catalyst.
a catalyst
catalyst-by lowering activation energy
A substance that speeds up the rate of a chemical reaction without being consumed in the process is called a catalyst. Catalysts provide an alternative pathway with lower activation energy for the reaction to occur, increasing the reaction rate without being altered themselves.
A catalyst
A reagent is a substance consumed during a chemical reaction to produce a specific product, while a catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. In other words, reagents participate in the reaction, while catalysts facilitate the reaction without being altered themselves.
This is called reaction rate.
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.
A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.
A catalyst is a substance that speeds up the rate of a chemical reaction.
a substance that inreases the rate of reation by lowering the activation-energy barrier. the catalyst is not used up in the reaction.
