The rate at which a reaction occurs. Related to molecular speed KE= ½ mv 2 ◦ Higher velocity (faster)= higher energy.
Chemical Reactions and Collision Theory Chemistry I 2007.
Temperature When temperature increases, the particles move faster causing more collisions & the reaction rate increases Simulation Simulation.
Equations Review
A _________ is a substance that speeds up a chemical reaction without being permanently consumed in the reaction. catalyst.
