Chemical Reactions depend on what. . .
Molecules must collide with one another head on with enough energy to break old bonds and form new ones.
2
New cards
What is activation energy
The minimum amount of energy needed for the particles to react
3
New cards
Rate of reactions depend on two things:
Frequency of collisions between particles
Energy with which particles collide
4
