Why does chemical reaction occur quicker at a higher temperature?

Answer 1

when temperature is raised ,the K.E. of molecules increases. Due to which molecules collide rapidly and consequently the rate of reaction increases. In other words: increasing the temperature increases both the rate at which collisions occur (because the molecules are moving around more) and the likelihood that the colliding molecules will react (because they're more likely to have sufficient kinetic energy to overcome the activation energy barrier).

Answer 2

Most chemical reactions occur more quickly at higher temperatures because most chemical reactions proceed through an "activated state" that can be formed only by reactants with more energy than average at standard temperature and pressure. The average energy of the molecules or atoms of any reactant is an average of a broad spectrum of individual energies for particular atoms and/or molecules, including some that are energetic enough to form the activated state. The effective reaction rate depends on the concentration of these higher-energy particular atoms or molecules, and this concentration depends on the concentration of total atoms and/or molecules and on ambient temperature for the reaction, with a greater concentration at higher temperatures.

Answer 3

The prticles have more kinetic energy at higher temperatures.

Answer 4

Collision theory, the particles are moving fast due to more energy from the heat allowing for more collisions causing substances to react faster.
