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.
1.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
Because the activation energy is different for different chemical reactions.
because 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
Between gas molecules, yes, it will.
Thr number of collisions between solute and solvent molecules is increased.
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.
The great the density the higher the air pessure.
Because it increases the probability of collisions
Liquids. There are more collisions, but the majority are at lower energies.
Collisions between solvent molecules and solute are more frequent at higher than lower temperatures.
It increases the number of collisions between molecules. :)
thermal effect
This is the ideal gas with no collisions between molecules..
Between gas molecules, yes, it will.
heating, stirring, surface area
"Activation energy to break chemical bonds is provided by what" Answer: High speed collisions between reactant atoms.
Thr number of collisions between solute and solvent molecules is increased.
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.
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
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.
