What collision theory explains
What collision theory explains
How reactions occur & why reactions happen at different rates
Basic requirement for reaction to occur
Basic requirement for reaction to occur
Particles must collide
Two conditions for successful collision
Two conditions for successful collision
Sufficient energy & correct orientation
Sufficient energy meaning (collision theory)
Sufficient energy meaning (collision theory)
Enough kinetic energy to overcome activation energy
Correct orientation meaning
Correct orientation meaning
Particles oriented properly so bonds break & new bonds form
Activation energy () definition
Activation energy () definition
Minimum energy reacting particles need for successful reaction
What activation energy represents
What activation energy represents
Energy barrier that must be overcome for reaction to occur
When reactions occur (energy requirement)
When reactions occur (energy requirement)
When particles have kinetic energy
What happens when particles collide with energy <
What happens when particles collide with energy <
They bounce off each other, no reaction occurs
Proportion of collisions leading to reaction
Proportion of collisions leading to reaction
Only a small proportion (most lack required energy)
