What is the definition of activation energy?
Energy needed to get a reaction started....
What energy transformation iis needed to start a helicopter?
forms of energy
What is required for a chain reaction to start?
Critical Mass is that minimum amount of fissionable material needed to maintain a chain reaction
What information does an energy diagram give?
It shows whether the reaction is exothermic or endothermic.
What is the difference between energy and activation energy?
Activation energy is the initial amount of energy required to initiate a a reaction where as the energy of reaction is the total amout of energy realeased or absorbed during the complete reaction which is also called as heat of reaction.
What do chemist call the energy needed to start a reaction?
The energy needed to start a chemical reaction is called the activation energy :)
Energy is the energy needed to start a chemical reaction?
The energy needed to statr a chemical reaction is the 'Activation Energy' , which is given the symbol (Ea).
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a 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 do chemists call the energy needed to get a reaction started?
The energy needed to start a chemical reaction is called the activation energy :)
What effect does an enzyme have on a activation energy needed to start a reaction?
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
It refers to the amount of energy needed to start the reaction?
Activation energy
Is Activation energy is the energy needed to start a chemical reaction?
Yes!
Energy needed to kick start a reaction is called what?
activation energy
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 can decreases the activation energy needed to start a reaction?
a catalyst
What does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
