The activation energy.
activation energy
When you rub the sticks together, you convert kinetic energy (from moving the sticks) to internal energy, or heat energy - the sticks will warm up. When the heat energy is sufficient to overcome the activation energy of the combustion (activation energy = minimum amount of energy required to start a chemical reaction), the chemical energy in the sticks/whatever you are combusting is converted to heat and light energy
A catalyst. It does do by decreasing the energy required for the reaction to take place (activation energy).
Depends on the equation. If it is similar to: Q = m*Cp*dT then Q = energy if it is similar to A= Ao * exp (-Q/RT) then Q is the activation energy
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
The carbon atom in CH3CN is sp hybridized.
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.
CH3CN is not an acid. It is a nitrile compound, also known as acetonitrile, which is a weak base in water.
That is called the activation energy or energy of activation (Ea).
The energy needed to get a reaction started is called activation energy.
CH3CH2CH3 (propane) has a lower boiling point than CH3CN (acetonitrile) because CH3CN has stronger dipole-dipole interactions due to its polar cyano group. This results in higher intermolecular forces in CH3CN, leading to a higher boiling point compared to propane.
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.
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.
Enzymes reduce activation energy, which is the energy required to start a chemical reaction. By lowering the activation energy, enzymes make reactions occur more readily and at a faster pace.
