What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
Which statement will be describe how enzymes effect chemical reactions?
Enzymes lower the activation energy needed to start a chemical reaction.
What describes the energy of activation?
Activation energy is the least amount of energy needed to start a chemical reaction. It is used to activate atoms or molecules in order for them to begin a chemical reaction.
Which is the best description of activation energy?
The amount of energy needed to start a chemical reaction. Source: Biology class
When a catalyst is present is more or less activation energy needed to start a chemical reaction?
When a catalyst is present, less activation energy is needed to start a chemical reaction. This is because the catalyst provides an alternative pathway for the reaction to occur, allowing it to proceed more readily. The catalyst achieves this by lowering the activation energy barrier for the reaction.
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What compound is needed to start a chemical reaction?
The initial compounds in a chemical reaction are called reactants.
What do chemist call the energy needed to start a reaction?
The energy needed to start a chemical reaction is called the activation energy :)
What substances is needed to start a chemical reaction?
reactants is your answer
Is it true that catalysts increase the activation energy needed to start a chemical reaction?
Catalysts actually lower the activation energy needed to start a chemical reaction. This makes the reaction happen more easily.
What energy is needed to start a chemical reaction?
Activation energy is the energy needed to start a chemical reaction by breaking the existing chemical bonds in the reactants before new bonds can form in the products. This energy barrier must be overcome for the reaction to proceed.
Is Activation energy is the energy needed to start a chemical reaction?
Yes!
Does catalysts inhibit the activation energy needed to start a chemical reaction?
no a catalyst starts the reaction
What function do catalysts perform in chemical reactions?
They speed a chemical reaction. Add: Catalysts lower the activation energy needed to start a chemical reaction.
What energy is the energy needed to start a reaction?
Activation Energy.
What does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
What is proteins that reduce the amount of energy needed to start a chemical reaction are called?
Proteins that reduce the amount of energy needed to start a chemical reaction are called enzymes. Enzymes act as catalysts by lowering the activation energy required for a reaction to occur, thus speeding up the reaction.
