What type of energy starts a reaction to overcome an energy barrier between reactants and products?
Activation energy
Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
If one molecule has more energy than another does it have a higher activation energy?
The activation energy refers to a chemical reaction.
Is activation energy for thermal and photochemical reactions same?
The definition of the activation energy is exactly the same -- the thermodynamic energy barrier that the reactant must pass over to convert to products. The difference between a thermal and a photochemical reaction is only where the reactants get the energy to get over this barrier. In a thermal reaction, that energy is given by the temperature, and is carried in excited rotational modes, higher kinetic energies and if hot enough, excited vibrational states. In a photochemical reaction, the activation energy is provided by photons, usually in the form of electronic excited states, but could also be vibrational or rotational. The concept of the activation barrier is identical in both cases.
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 barrier?
The question is this "what is an energy barrier?" My answer: First of all, activation energy is energy that is needed to start a reaction and barrier means to block so then energy barrier means to block energy.
What do we call the barrier to a chemical reaction?
The Activation Energy.
Activation energy barriers?
The activation energy is the amount of energy needed to start a reaction. If the reactants have less than that amount the reaction will not occur. In this way it acts as a barrier that prevents a reaction unless there is enough energy to break it.
Reactants capable of interacting to form products in a chemical reaction must first overcome a thermodynamic barrier known as the reaction's?
activation energy
What type of energy starts a reaction to overcome an energy barrier between reactants and products?
Activation energy
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.
Is Activation energy the minimum energy needed for a reaction to start?
No, the opposite. The lower the activation barrier the faster the reaction goes. That is how a catalyst speeds up the reaction: by lowering the activation energy.See the Web Links for more information.
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 does a chemical reaction starts?
A reaction occurs when 2 particles collide with sufficient energy to overcome the activation barrier and then react.
Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
If one molecule has more energy than another does it have a higher activation energy?
The activation energy refers to a chemical reaction.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
