In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
The reaction is spontaneous at low and high temperatures but at room temperature its rate is so slow that it is negligible. The increase in temperature, as created by a match, allows the reaction to start and then it heats itself, because it is exothermic. That is valid for many other fuels, such as methane, butane, hydrogen... 4) Solvent: Many reactions take place in solution and the properties of the solvent affect the reaction rate.
