Why do most chemical reaction rates increases rapidly as the temperature rises?
1
The fraction of the molecules with kinetic energy greater than the activation energy increases rapidly with temperature
2
The average kinetic energy increases as temperature rises
3
The activation energy decreases as the temperature rises
4
More collision take place between particles so that the reaction can occur
