It generally comes from the kinetic energy of the molecules, which is another way of saying "heat".
Yes. Light can provide activation energy. In fact some chemicals must be stored in the dark to prevent unwanted reactions.
Lowering a chemical reaction's activation energy is the minimum energy required for particles to successfully collide and forms bonds.
They lower the activation energy needed 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.
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.
That is called the activation energy or energy of activation (Ea).
The energy needed to get a reaction started is called 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.
Activation energy describes the energy that is required to get chemical reactions started.
Catalysts lower the activation energy of reactions, usually by providing an alternate reaction pathway, or mechanism that does not require so much energy. Having a lower activation energy means that less energy has to be transferred to each molecule in order for the reaction to progress.
Activation energy is energy or power conducted that can be instantly activated for use when flick a light switch you used activation energy.
This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.
