Why don't all collisions between reactant molecules lead to product formation?

For most reactions, chemical reaction requires that molecules acquire greater than average energy. This is called the "activation energy", and only some collisions impart a sufficient amount of energy.

∙ 13y ago1.the collision must involve enough energy to produce the reaction; i.e., the collision energy must equal or exceed the activation energy
2. the relative orientation of the reactants must allow formation of any new bonds necessary to produce products
Wiki User
∙ 10y agoBecause the activation energy is different for different chemical reactions.
Wiki User
∙ 13y agobecause molecules need to collide in a certain arrangement to react. Also, the molecules need to have enough kinetic energy (more than the activation energy of the reaction) in order to react

Will higher temperatures cause more collisions?
Between gas molecules, yes, it will.
Why does stirring increase the rate of dissolution?
Thr number of collisions between solute and solvent molecules is increased.
How does increasing the gas pressure increase the reaction rate?
Yes, because as pressure increases, the collisions between gas particles would occur more frequently and with more force. Therefore, the amount of potential energy would increase, and it would take a shorter time for the activation energy to be reached.
Why does an increase in the number of molecules increase the pressure?
The great the density the higher the air pessure.
Why does increasing the concentration of a reactants increase the reaction rate?
Because it increases the probability of collisions
Are collisions more common between gas molecules or liquid molecules?
Liquids. There are more collisions, but the majority are at lower energies.
Are collisions between solvent molecules and solute are more frequent at lower or higher temperatures?
Collisions between solvent molecules and solute are more frequent at higher than lower temperatures.
How does this increase the rate of the reaction?
It increases the number of collisions between molecules. :)
What a temperature increases affect collisions between molecules?
thermal effect
What happenes to the particels of a gas when there are fewer of them?
This is the ideal gas with no collisions between molecules..
Will higher temperatures cause more collisions?
Between gas molecules, yes, it will.
How do you increase the number of collisions between molecules?
heating, stirring, surface area
Activation energy to break chemical bonds is provided by what?
"Activation energy to break chemical bonds is provided by what" Answer: High speed collisions between reactant atoms.
Why does stirring increase the rate of dissolution?
Thr number of collisions between solute and solvent molecules is increased.
How does increasing the gas pressure increase the reaction rate?
Yes, because as pressure increases, the collisions between gas particles would occur more frequently and with more force. Therefore, the amount of potential energy would increase, and it would take a shorter time for the activation energy to be reached.
What is effusions?
effusion is the process where individual molecules flow through a hole without collisions between molecules. effusion is the process where the gas molecules are passed through a small opening to an evacuated chamber
Assumption of kinetic theory of gas?
The volume occupied by gas molecules is negligible when compared to volume occupied by the gas.The collisions between gas molecules-gas molecules and gas molecules-walls of the container are perfectly elastic.
