When molecules of the reactant hit each other, only a certain percentage of the collisions cause a chemical change.If the molecules are moving too slowly, they will bounce off each other. There will be no reaction.If the molecules are moving rapidly but do not collide with the correct orientation, they will again bounce off each other. There will be no reaction.

I hope this helps

What affect the rate at which solid and liquid reaction occurs?

aleksklad [387]

Answer:

Surface area

Explanation:

Surface area affect the rate at which solid and liquid reaction occur because when the surface area is increase, there will be increase in chemical reaction which is as a result of particles size of the solid. When .there is decrease in the particle size of the solid, the surface area will increase and this is as a result of increase in the energy that is required by the particle size.

Before entering the cyclotron, the particles are accelerated by a potential difference V. Find the speed v with which the partic

vesna_86 [32]

Answer:

Speed, $v=\sqrt{\dfrac{2qV}{m}}$

Explanation:

The device which is used to accelerate charged particles to higher energies is called a cyclotron. It is based on the principle that the particle when placed in a magnetic field will possess a magnetic force. Just because of this Lorentz force it moves in a circular path.

Let m, q and V are the mass, charge and potential difference at which the particle is accelerated.

The work done by the particles is equal to the kinetic energy stored in it such that,

$qV=\dfrac{1}{2}mv^2$

v is the speed with which the particles enter the cyclotron

So,

$v=\sqrt{\dfrac{2qV}{m}}$

So, the speed with which the particles enter the cyclotron is $v=\sqrt{\dfrac{2qV}{m}}$ . Hence, this is the required solution.
