Temperature increases the number of collisions. When the temperature is increased, the particles all move quicker. If they're moving quicker, they're going to have more collisions. Reactions only happen if the particles collide with enough energy. At a higher temperature there will be more particles colliding with enough energy to make the reaction happen.
[IMAGE] Faster collisions increase the rate of reaction High temperatures also increase the energy of the collision, because it makes all the particles move faster. Faster collisions are only caused by increasing the temperature. Reactions only happen if the particles collide with enough energy. At a higher temperature there will be more particles colliding with enough energy to make the reaction happen. This initial energy is known as the activation energy, and it is needed to break the initial bonds.
The more you have, the faster the reactions you will get. Concentration - The concentration is how strong the acid is. The stronger the acid is, the faster the reaction is, because the higher the concentration the more particles there are which mean they are more likely to collide. For any reaction that takes place particles must collide. The way all rates of reaction are increased is by an increase in the particles colliding with more energy.
The more molecules of reactant there are in a given volume, then the higher the probability of a collision. Temperature. Because the molecules in the solutions will move faster when they are hot, higher temperatures also lead to faster reaction rates. It is the same as children in a confined playground - they take up more space every second if they move fast, so are more likely to collide. Stirring.Because stirring moves the molecules around faster, they are more likely to collide and therefore react.
This leads to more collisions. In addition, particles have more kinetic energy, so more collisions will lead to a reaction. *The effect of the surface area on the rate of reaction is, when one of the reactants is a solid, the reaction must take place on the surface of the solid. By breaking the solid into smaller pieces, the surface area is increased, giving a greater area for collisions to take place and so causing an increase in the rate of reaction. *The effect of using a catalyst on the rate of reaction is that it will speed up the rate of reaction.
Particles have to collide in order to react, and the have to collide hard enough as well. This is called the collision theory. When the temperature is increased the particles all move quicker. If they are moving quicker then they are going to have more collisions. Higher temperature also increases the energy of the collisions, because it makes all the particles move faster.

Pressure. 1. When the temperature is increased all the particles move quicker, therefore there are more collisions. 2. If the solution is made more concentrated there will be more particles of the reactant colliding between the water molecules which makes collisions between the reactants more likely.
Factors/ Variables Catalyst - A catalyst is a substance which increases the speed of a reaction without being changed or used up in a reaction. The catalysis works by giving the reacting particles something to stick to where they can collide into each other; this increases the number of collisions. Concentration - If the solution is made more concentrated it means there are more particles of reactant between the important particles are more likely. Temperature - When the temperature is increased the particles all move quicker, if they are moving quicker, they are going to have more collisions. We used a thermometer to control this.
The more crowded the particles are, the more often we should expect them to bump into each other. Surface Area A solid in a solution can only react when particles collide with the surface. The bigger the area of the solid surface, the more particles can collide with it per second, and the faster the reaction rate is. You can increase the surface area of a solid by breaking it up into
