How Does Temperature Affect The Rate Of Reaction

‘Kinetics’ is the study of chemical reactions. The speed of a reaction can vary depending on many variables such as the nature of the reactants, particle size, concentration and temperature. For a chemical reaction to occur, there must be a collision between reactants. The reaction rate is slower when the reactants are large and complex molecules because it takes longer for the molecules to combine together creating a chemical reaction. More than 2000 years ago, Democritus, who was a philosopher from Greece suggested that matter is made up of tiny particles too small to be seen. He thought that if you kept cutting a substance into smaller and smaller pieces, you would eventually come to the smallest possible particles.
The rate of a chemical reaction depends on the area of the surface area. A solid that is present in a chemical solution can only react when particles collide with the surface of the solid. If the area of the solid surface is made bigger then more particles can collide with it per second and the rate of reaction increases. You can increase the surface area of a solid by breaking it down into smaller pieces. A solid that is broken down into a powder has the largest surface area and therefore has the fastest reaction
The increase of the temperature causes the molecules to move faster, causing them to crash into one another, creating a chemical reaction. Increasing the temperature not only increases the number of collisions but also increases the number of collisions that are able to transfer enough energy to cause a reaction to take place. This is because they have more energy and when they bounce around, they are more likely to collide. But not all temperature changes make particles move faster, when the temperature is lowered, the molecules move slower and collide less. A colder temperature drops the rate of reaction whereas a hotter temperature increases the rate of
