Why does an increase in temperature result in an increase in reaction rate?

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.

When we increase the temperature in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases collision between the particles and the rate of reaction.
