Chapter 8 - Rates Of Reaction Flashcards
1
Q
Rate of reaction is
A
Amount of reactant used/time
2
Q
Activation energy
A
Minimum energy needed to react
3
Q
Factors increasing frequency of collisions
A
Temperature, concentration, surface area of solid, catalyst and pressure of gases.
4
Q
Increasing temperature
A
Increases rate of reaction because particles collide more frequently and more energetically.
5
Q
Increasing pressure
A
Puts more molecules into the same volume so they collide more frequently.
6
Q
Catalysts
A
Lower the activation energy and provide an alternative reaction pathway to speed up reactions.
