What Activation energy play in a chemical reaction?
It indicates how likely a reaction might be, but there are no hard rules. Low activation energy indicates that the reaction is likely to take place spontaneously. In most cases, the reaction must be exothermic as well. There are lots of exceptions to these simple rules. For any reaction to occur, the reactants must gain at least the activation energy.
Does a chemical reaction always require energy to start?
Yes, every chemical reaction requires activation energy, though in some cases the ambient heat of room temperature is enough to provide that energy.
How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
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.
What is the activation energy needed for a chemical reaction decreased by?
The activation energy is decreased by a catalyst.
What is it called when energy is required to start a chemical reaction?
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
How is activation energy related to bond energy?
Activation energy is the minimum energy required for a chemical reaction to occur. It is related to bond energy because breaking chemical bonds and forming new bonds requires energy, which contributes to the activation energy of a reaction. Bonds with higher bond energy are more stable and require more energy to break, hence increasing the activation energy of the reaction.
What is a sentence using the word activation energy?
Activation Energy is the required energy needed in order for a chemical reaction to start.
Is activation energy added or just there?
Activation energy is the amount of energy that should be gained by potential reactants, for a reaction to occur. A reaction can be occurred by reducing the activation energy of the reaction or increasing the activation energy of the reactants. Activation energy should be added.
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 the relationship between an energy diagram and activation energy in a chemical reaction?
An energy diagram shows the energy changes that occur during a chemical reaction. Activation energy is the minimum amount of energy required for a reaction to occur. In the energy diagram, the activation energy is the energy barrier that must be overcome for the reaction to proceed. A higher activation energy means a slower reaction, while a lower activation energy means a faster reaction.
Do Enzymes increase or decrease the Activation Energy of a Chemical Reaction?
Enzymes decrease the activation energy of a chemical reaction. They do this by providing an alternative pathway with a lower activation energy that allows the reaction to proceed more rapidly.
What is the significance of the activation energy curve in the context of chemical reactions?
The activation energy curve shows the energy needed to start a chemical reaction. It is significant because it determines the rate at which a reaction occurs. Higher activation energy means a slower reaction, while lower activation energy means a faster reaction.
What is activation enery?
Activation energy is the amount of energy that a chemical reaction requires to occur.
What activation energy is needed for a chemical reaction is decreased by?
The activation energy is decreased by a catalyst.
