The activation energy is decreased by a catalyst.
What else can I help you with?
Definition energy needed for a chemical reaction is decreased by what?
The energy needed for a chemical reaction, known as activation energy, can be decreased by the presence of a catalyst. Catalysts work by providing an alternative reaction pathway with a lower activation energy, thereby increasing the reaction rate without being consumed in the process. Additionally, factors such as increasing temperature or concentration can also decrease the effective activation energy needed for a reaction to occur.
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.
Start up energy of a chemical reaction?
The activation energy is the minimum amount of energy required to initiate a chemical reaction. It helps to break the existing bonds in reactant molecules and start the formation of new bonds in the product molecules. Lowering the activation energy can increase the reaction rate.
How does an enzyme catalyze a chemical reaction in regards to activation energy?
Any catalyst will make a chemical reaction easier or quicker to happen by lowering the activation energy. On a energy diagram, you will see a lower "hill" for activation energy, which corresponds to less energy required to begin the reaction.
What activation energy is needed for a chemical reaction is decreased by?
The activation energy is decreased by a catalyst.

Additionally, factors such as increasing temperature or concentration can also decrease the effective activation energy needed for a reaction to occur.
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.
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.
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 does the amount of energy affect during a chemical reaction?
A chemical reaction need an activation energy to start.
