Why are most particle collisions ineffective?
comparing to an atom , the particles of it are very very small , their collision may be effective inside that atom but we could not measure the effectiveness since it takes place for a very very small time (fempto seconds) than the size of electron. Hence we think that the particle collisions are ineffective .
Does every collision between reacting particles leads to products?
For a reaction to take place, the reactants must have sufficient energy and have correct orientation when they collide. So, the reason why all collisions don't lead to reaction is that the collisions do not satisfy these conditions.
Why does hot water increase the rate of reaction?
In order for a chemical reaction to occur, there must be a certain amount of energy to break, and then reform chemical bonds. The collision of particles must also occur at the correct angle for a chemical reaction to occur. Heat is essentially the energy a substance has, so the higher the temperature, the higher the energy of of the particles. If the particles have a higher energy, they move around faster, therefore increasing the probability of a successful collision. The energy (or velocity) of particles is also higher, therefore creating higher chance that there is enough energy in the chemical collision for the reaction to occur.
Do alpha particles and helium atoms have same electrons?
No. The difference between them is that helium atoms have electrons, and alpha particles don't.
What happens if a pair of colliding molecules possesses less energy than Ea?
If the collision has less energy than Ea (which is activation energy,) then the particles will not have sufficient energy to react.

Which is described as an unstable short lived structure caused by the effective collision of particles?
Activated complex
What transfers heat by collision of particles?
energy
Is it possible that both of the particles can be at rest after collision?
Yes.
According to collision theory increasing the concentration of the reactants in a chemical reaction increases?
A.the rate of collisions between two particles.
What is the transfer of heat through a material by the collision of particles?
"conduction"
What is particle collision?
Particle collision usually refers to two subatomic particles slamming into each other at high speeds causing them to break into smaller particles. These speeds are created by particle accelerators.
What is the force caused by collisions of particles?
Gravity is the force caused by the collision of particles.
What happens when the gas particles are moving fast to its energy and its temperature?
exerting lots of kinetic energy into gas particles speeds up the collision theory
How does the factor concentration affect reaction rate?
increasing concentration increases rate of reaction as there are more particles so there is a larger chance of collision,it increases the probability of collision of the reactants.
How does concentration factors affect reaction rate?
increasing concentration increases rate of reaction as there are more particles so there is a larger chance of collision,it increases the probability of collision of the reactants.
Particles that are visible in the light microscope and move erratically by molecular collision represent what process?
Brownian motion
