What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What best explains the role of a catalyst in a chemical reaction?
A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does this by providing an alternative reaction pathway with a lower energy barrier. The catalyst itself is not consumed in the reaction and can be reused multiple times.
What is a chemical substance that helps control reactions?
A catalyst is generic term used to influence rates of reaction. The catalyst lowers the activation energy required to start the reaction. In biology, catalysts are called enzymes.
What is a catalyst?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It lowers the activation energy required for the reaction to occur, thereby speeding up the reaction. Catalysts remain unchanged at the end of the reaction and can be used multiple times.
What is a substance that enables a chemical reaction to proceed under different conditions?
A catalyst is a substance that enables a chemical reaction to proceed under different conditions. It lowers the activation energy required for the reaction to occur, allowing it to happen more quickly or at a lower temperature or pressure. The catalyst itself remains unchanged in the reaction and can be reused multiple times.

This substance is a catalyst.
What term describe a substance that lowers the amount of energy needed to start a chemical reaction?
Catalyst
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
How does the addition of catalyst affect the energy of activation of chemical reaction?
It lowers it, so the reaction is faster.
How does the addition of a catalyst affect the energy of activation of a chemical reaction?
It lowers it, so the reaction is faster.
How does the addition of a catalyst affect the energy activation of a chemical reaction?
It lowers it, so the reaction is faster.
What term is given to a substance which speeds up a reaction and is unchanged after the reaction?
Catalyst- lowers the activation energy of a reaction but is not consumed.
What does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
What does a enzyme do A Adds heat to a reaction speeding it up B Lowers the activation energy of a reaction C Cools a reaction slowing it down D Raises the activation energy of reaction?
B. Lowers the activation energy of a reaction. Enzymes facilitate chemical reactions by decreasing the energy needed to start the reaction, thus speeding up the overall process.
