12 cards from this deck
Theory explaining how conditions affect reaction speed
Concentration, temperature, surface area, catalysts
Only a small fraction
Reactant particles must collide
Must have enough energy (activation energy)
Minimum energy needed for a reaction to occur
Increase collision frequency or particle energy
Number of particles doubles
Collision frequency doubles
Rate of reaction doubles
More particles, so more frequent collisions
Constantly moving and colliding with each other
