Activation Energy.
What else can I help you with?
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 is the definition of activation energy?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. It represents the energy barrier that must be overcome for reactant molecules to transform into products. Higher activation energy results in slower reaction rates.
What does the energy hill represent on a energy diagram?
The energy hill on an energy diagram represents the activation energy needed for a chemical reaction to occur. It shows the energy barrier that must be overcome for the reaction to proceed from reactants to products. The height of the hill indicates the energy input required for the reaction to take place.
Where does the energy come from that is needed for an endothermic reaction the products or the reactants?
The energy needed for an endothermic reaction comes from the surroundings, not from the reactants or products. This energy is absorbed during the reaction to break bonds and allow new bonds to form, resulting in the overall absorption of heat.
What energy transformation iis needed to start a helicopter?
To start a helicopter, the energy transformation needed involves converting chemical energy stored in the fuel into mechanical energy. This is achieved by the combustion of fuel in the engine, which creates the necessary rotational motion to start the helicopter's rotor blades.
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 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 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?
The energy needed to kick start a reaction is called activation energy. It is the minimum amount of energy required for a chemical reaction to occur. It is usually provided in the form of heat or light energy.
What does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the 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
Energy is the energy needed to start a chemical reaction?
Activation energy is the minimum amount of energy required for a chemical reaction to occur. It acts as a barrier that reactants must overcome to form products. This energy is needed to break bonds in the reactant molecules before new bonds can form in the products.
The energy needed to start a chemical reaction is termed as whatg type of energy?
ActivAtiOn!!!
The minimum amount of energy needed to start a chemical reaction is called?
The activation energy.
