How can you determine collision rate from Langevin theory?
Collision rate can be determined from Langevin theory by calculating the frequency of collisions between the particle and surrounding particles. This can be done by considering the particle's diffusion coefficient, the size of the particle, and the density of the surrounding medium. By using these parameters, one can estimate the collision rate based on the Langevin equation.
What is the relation between transition probability and cross section?
The transition probability is the likelihood that a particle will change from one state to another during a collision, whereas the cross section represents the effective area that the particle presents to a collision. The transition probability is related to the cross section by the formula: transition probability = cross section * particle flux, where the particle flux is the rate at which particles are incident on a target.
What must be done to increase the rate of reaction?
Temperature
How can a photon have frequency?
A photon behaves both as a wave and a particle. The frequency of a photon is related to its energy by the equation E = hf, where E is energy, h is Planck's constant, and f is frequency. So, the frequency of a photon is a characteristic of its wave-like nature.
Can you change the rate of a chemical reaction by changing the particle size?
In hetrogeneous reactions (where the reactants are in different states) the size of the particles of a solid may change reaction rate, since the surface is where the reaction takes place, and the surface area is increased when the particles are more finely divided. In general, the smaller the particles the faster the reaction

You can slow down the rate of reaction by?
You can slow down the rate of a reaction by decreasing the temperature, decreasing the concentration of reactants, increasing the activation energy needed for the reaction to take place, or using an inhibitor to interfere with the reaction process.
Is the energy of collision between two reactant particles is frequently absorbed by collision with a third particle?
Yes, the energy of collision between two reactant particles can be absorbed by collision with a third particle. This process, known as collision-induced relaxation, can lead to the redistribution of energy among the molecules involved in the collision.
What is the period of a particle that has a frequency of 315 hertz?
The period of a particle is the inverse of its frequency. Therefore, for a particle with a frequency of 315 Hz, the period can be calculated as 1/315 Hz, which equals 0.00317 seconds.
What is the frequency of a particle?
The frequency of a particle is a measure of how often it oscillates or vibrates within a system. In quantum physics, the frequency of a particle can also refer to the number of wave cycles that pass a fixed point in a unit of time. The frequency of a particle can impact its energy and behavior in various physical phenomena.
What is the cyclotron frequency formula used to calculate the frequency of a charged particle moving in a magnetic field?
The cyclotron frequency formula is given by f qB / (2m), where f is the frequency, q is the charge of the particle, B is the magnetic field strength, and m is the mass of the particle.
What is meant by cyclotron frequency?
Cyclotron frequency refers to the frequency at which a charged particle orbits in a magnetic field. It is determined by the strength of the magnetic field and the mass and charge of the particle. The cyclotron frequency is an important parameter in understanding the behavior of charged particles in magnetic fields, such as in particle accelerators.
What type of nuclear decay results in the atomic number decreasing by two and the mass decreasing by two?
Emission of an alpha particle.
How does particle movement occur?
by the collision of atoms or internal collisionbetween the atoms
What is the significance of the cyclotron frequency in the operation of a cyclotron particle accelerator?
The cyclotron frequency is important in a cyclotron particle accelerator because it determines the rate at which charged particles spiral and gain energy in the magnetic field. This frequency must match the frequency of the accelerating electric field to ensure efficient particle acceleration.
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.
Each fundamental atomic particle has an opposite particle A collision of these opposites will result in the annihilation of each particle These types of particles are referred to as?
Anti-matter. Antimatter.
