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 happens to the reaction rate if the activation energy gets smaller?
If the activation energy decreases, the reaction rate typically increases because a lower activation energy makes it easier for the reactant molecules to overcome the energy barrier and form products. This allows the reaction to proceed more rapidly at a given temperature.
What term is used to describe the minimum amount of energy required in order for a reaction to proceed?
This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a 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.
What is the activation energy for crystal violet and NaOH?
The activation energy for the reaction between crystal violet and NaOH would depend on the specific reaction being considered. Generally, this information would be obtained through experimental measurements.
What happens when an enzyme and a substrate interact at an active site?
Activation energy is reduced! :)
What happens to the rate constant as activation energy increase?
The rate constant decreases.
What happens to a rate constant as activation energy increases?
As activation energy increases, the rate constant typically decreases. This is because a higher activation energy means that fewer molecules have sufficient energy to overcome the energy barrier for the reaction, resulting in a slower reaction rate. According to the Arrhenius equation, the rate constant is inversely related to the activation energy, highlighting this relationship.
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 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 happens to the reaction rate if the activation energy gets smaller?
If the activation energy decreases, the reaction rate typically increases because a lower activation energy makes it easier for the reactant molecules to overcome the energy barrier and form products. This allows the reaction to proceed more rapidly at a given temperature.
What happens when activation energy is in presence of an enzyme?
When activation energy is in the presence of an enzyme, the enzyme can lower the activation energy barrier required for a chemical reaction to occur. This allows the reaction to proceed at a faster rate and with lower energy input. The enzyme does this by stabilizing the transition state of the reaction, making it easier for the substrate molecules to react.
What is the minimum energy required for molecules to react with each other called?
That is called the activation energy or energy of activation (Ea).
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.
What happens to catalysts during chemical reactions?
it lowers the amout of activation energy needed to start the reaction.
What happens if the amount of energy that is absorbed by the reactants is less than the activation energy?
If the energy absorbed by the reactants is less than the activation energy, the chemical reaction cannot proceed. Activation energy is the minimum energy required to break bonds and initiate a reaction. Without sufficient energy, the reactants remain in their original state and do not transform into products. Therefore, the reaction is effectively stalled until enough energy is supplied.
