3.1.5 Reaction Kinetics Flashcards
(5 cards)
1
Q
collision theory
A
Reactions can only occur when collisions take place between particles having sufficient energy.
This minimum energy is called the activation energy.
2
Q
activation energy definition?
A
the minimum energy which particles need to collide to start a reaction
3
Q
how can a reaction go to completion if few particles have energy greater than activation energy?
A
particals can gain energy through collisions
4
Q
what does a catalyst do?
A
provide an alternative route or mechanism with a lower activation energy hence increasing reaction rates
5
Q
what is the reason that causes a small increase in temperature to lead to a large increase in rate of reaction?
A
a greater proportion of particles have energy greater than or equal to activation energy
