What is the minimum amounth of energy required for a reaction occur?
The minimum amount of energy needed for a reaction to take place is called the activation energy.
Does an exothermic reaction occur when there is a net release of energy?
Exo means 'outside' and thermic means 'heat'. When heat is released in a reaction, its called an Exothermic reaction. Now, answering the question, the energy required for the reaction to occur is less than the total energy released. So, the extra energy gets converted into heat or light. So, yes there is a net release of energy in an exothermic reaction.
What is the amount of energy a reaction needs to take place?
The amount of energy a reaction needs to take place is called activation energy. When this much energy is present, a chemical reaction can occur.
What is reactions that occur when more energy is released forming new bonds than is required to break bonds in the initial reactions?
When more energy is released than that which is provided, this is referred to as an exothermic reaction.
How do enzymes affect standard free energy?
Standard free energy doesn't change with an enzyme. Rather, the enzyme acts to redirect that reaction in a particular way, lowering the required energy for the reaction to occur but not changing the energy amount involved.
How a enzymes catalyze a chemical reaction?
they reduce the activation energy required for the reaction to occur
Why activation energy is referred in the definition of enzymes?
The chemical term activation energy is the amount of energy required for a chemical reaction to take place. For more information about different chemical contact a scientists or science professor in one's area.
What are the benefits of catalysts?
lower activation energy required for chemical reaction to occur
How does enzymes catalyze reactions?
they reduce the activation energy required for the reaction to occur
What energy is required for the reaction to occur?
Activation energy. The kinetic energy from collisions between particles is used to reach the transition state
What is the minimum amounth of energy required for a reaction occur?
The minimum amount of energy needed for a reaction to take place is called the activation energy.
Does an exothermic reaction occur when there is a net release of energy?
Exo means 'outside' and thermic means 'heat'. When heat is released in a reaction, its called an Exothermic reaction. Now, answering the question, the energy required for the reaction to occur is less than the total energy released. So, the extra energy gets converted into heat or light. So, yes there is a net release of energy in an exothermic reaction.
If heat is required for a reaction to occur what type of reaction is it?
Endothermic
To make a chemical reaction occur the activation energy is the energy that?
initiates the reaction
How does activation energy affect the progress affect the progress of a reaction?
The reaction will not occur unless the activation energy is met.
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.
Enzymes speed up chemical reactions by?
by lowering the activation energy of reactions
