What else can I help you with?
The amount of energy which a system has to have in order for a chemical change to take place?
The activation energy.
What represents the highest energy point on an energy diagram?
activation energy
What two energy transformations happen when you rub two sticks together and fire is started?
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
What speeds up reactions?
A catalyst. It does do by decreasing the energy required for the reaction to take place (activation energy).
In this equation what does Q repressent?
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
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 hybridization of the carbon atom in CH3CN?
The carbon atom in CH3CN is sp hybridized.
What is the minimum amount of energy needed to start a chemical 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.
Is CH3CN and acid?
CH3CN is not an acid. It is a nitrile compound, also known as acetonitrile, which is a weak base in water.
What is the minimum energy required for molecules to react with each other called?
That is called the activation energy or energy of activation (Ea).
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.
Does ch3ch2ch3 have a higher or lower boiling point than ch3cn?
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.
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.
What term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
Which is a best definition of activation energy?
Activation energy is energy or power conducted that can be instantly activated for use when flick a light switch you used 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.
What kind of energy do enzymes reduce?
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.
