How does temperature affect rate of reaction?

Answer 1

The higher temperature will cause the particles to move faster and to increase the number and strength of the collisions. So, a lower temperature will slow the speed at which the particles move and decrease the number and strength of the collisions.

To add to the answer above, higher temperature gives off more energy (kinetic) to the particles. More energy allows the particle to collide with other particles with more energy. And they will collide much faster, which will eventually break the bond between them.

Answer 2

A higher temperature makes molecules move faster. As the molecules move faster they rapidly bounce into each other. The faster moving molecules speeds up the reaction.

Answer 3

if the reaction is exothermic (creates heat) then adding heat will cause the reaction to run in the reverse direction if the reaction is endothermic (requires heat) then heat will speed it up
