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 is the truth about catalysts?
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
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 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.
How does activation energy effect the progress of a reaction?
The reaction will not occur unless the activation energy is met.
What is lowered to speed up a chemical reaction?
Activation energy is lowered to speed up a chemical reaction.
What happens to the reaction rate if the activation energy gets smaller?
When activation energy is lowered (e.g. by using a catalyst) the reaction rate increases (at the same temperature)
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 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 truth about catalysts?
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
What catalysts the amount of activation energy needed?
Using catalysts the activation energy is lowered.
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.
Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
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 does an enzyme do to the activation energy needed to start a chemical reaction?
Enzymes are catalysts, they reduce the activation energy.
