The energy the molecules must have in order to react
What else can I help you with?
How do changes in temperature and activation energy compare in how they affect reaction rate Apex?
Changes in temperature and activation energy have opposite effects on reaction rate.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
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.
What is the minimum amount of energy needed to start a chemical reaction?
The minimum amount of energy needed to start a chemical reaction is called the activation energy. It is the energy required to break the bonds in reactant molecules and initiate the reaction. Once this energy barrier is overcome, the reaction proceeds without additional energy input.
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 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 do changes in temperature and activation energy compare in how they affect reaction rate Apex?
Changes in temperature and activation energy have opposite effects on reaction rate.
What it the term used to describe the energy needed to get a reaction started?
The energy needed to get a reaction started is called activation energy.
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 is activation energy How does a catalyst affect activation energy?
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.

The minimum amount of energy needed to start a chemical reaction is called the activation energy. It is the energy required to break the bonds in reactant molecules and initiate the reaction. Once this energy barrier is overcome, the reaction proceeds without additional energy input.
How does activation energy affect the progress affect the progress of a reaction?
The reaction will not occur unless the activation energy is met.
How does activation energy effect the progress of a reaction?
Activation energy is the minimum amount of energy required to initiate a chemical reaction. A lower activation energy means that more molecules have enough energy to react, leading to a faster reaction rate. Conversely, a higher activation energy requires more energy input and can slow down the reaction rate.
What does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
How does activation energy affect the length of a reaction?
as activation energy decreases, reaction will finish faster (length of reaction decreases)
