Collision theory

Can someone please explain collision theory and how temperature relates to it?

I'm not sure that we need to know about the details of the collision theory, but temperature is related to collision between particles because an increase in the number of collisions increases the kinetic energy of each particle, which is a measurement for temperature.

Collision theory is when different reactions occur at different rates. This suggests ways in which to change the rate of a reaction. For a chemical reaction to occur in the Collision theory, the reacting particles have to collide with one another. The reacting particles can collide without reacting. For an endothermic reaction, when the temperature is higher, the particles move around more, so they are more likely to collide in a way that it meets the criteria of the collision theory.

Collision theory basically operates under the idea that, for compounds to react with each other, they have to physically touch. Since temperature is a measure of average kinetic energy, then a higher temperature means a higher average kinetic energy. A higher kinetic energy means that molecules are moving around faster, so their chance of running into each other in a given span of time is higher, meaning they react more quickly.

Collision theory is the theory that for gas particles to react, they have to collide with each other. Since increasing temperature, increases the kinetic energy of the particles, they are more likely to collide, therefore the reaction rate increases.

Collision theory basically states that in order for gas particles to interact with one another they collide. With increasing temperatures, there is an increase in chaos and kinetic energy so the rate of the reaction will increase as well.

Temperature is a measurement of the average kinetic energy of the particles in a sample. At a higher temperature, the particles have more energy, they are moving around more/faster. Therefore they will collide more. According to collision theory, particles have to collide (in certain ways- think mechanisms) for reactions to occur. If there are more collisions in general due to higher energy, there is more probability that there will be the right kind of collisions for a reaction to occur.

The collision theory is specifically applied to gases. It states that for gas molecules to interact with each other, collisions are necessary to create physical contact among them. However, not all collisions result into a chemical change or reaction because the molecules may not contain enough internal energy to overcome the activation energy or the reaction is not favorable. So the reaction rate is closely related to the frequencies of effective collisions. Increasing the temperature cause more collisions.
