Kinetics Flashcards
Definition of Rate of Reaction
The change in concentration/ amount of reactant/product per unit time
Amount of reactant used or product made / Time
Definition of Activation Energy
Minimum amount of energy required for a reaction to occur
What happens to the Rate of reaction when temperature increases (4)
-> Higher temp - higher average kinetic energy = higher velocity
-> particles collide more frequently
-> Many more particles have energy of or higher then the activation energy
-> rate of reaction increases as there are more successful collisions per second
How does Pressure affect rate of reaction?
How does Concentration affect rate of reaction
Rate of reaction increases
Particles are closer together
Collide more often
Higher chance of successful collision
How does a Catalyst affect rate of reaction?
