Because at higher temperatures, there is more energy in the reactants. With more energy, they move faster. This makes them more likely to collide, causing a chemical reaction. This also results in more energy at the impact, making it easier and more likely that the reactants achieve the activation energy required for the reaction to happen. Also, in decomposition reactions, there is more energy available to complete the reaction, and the "binding states" of the reactants are under more stress (so they are easier to "break").

2 factors spring to mind,

1: The concentration affects the speed because with more particles in a area collisions are more likely to happen and so speeds up the reaction

2: The pressure because with a higher pressure there is less room for the particles to move around in and so collisions are more likely speeding up the reaction

When you add a catalyst to the reaction or if you heat the items up.

Temperature rise

Use of catalyst

the guy above me is dumber than dog crap.

another thing that will do this is the pressure
