Why does increasing the temperature of a reaction increase the speed of the reaction?

Answer 1

Increasing the temperature of a reaction increases the speed of the reaction because it provides more thermal energy to the molecules of the reactants. This extra energy increases the kinetic energy of the molecules, which causes them to move faster and collide more frequently. Additionally, the increased temperature can break some of the bonds within the reactant molecules, making them more reactive and easier to react with other molecules. The combined effect of increased collision frequency and increased reactivity of molecules leads to an overall increase in the rate of the reaction.
