Rate of reactions Flashcards
1
Q
State the collision theory
A
Reacting particles must collide with sufficient energy to overcome activation energy for a successful reaction to occur
2
Q
Factors affecting the rate of chemical reaction
A
Concentration, particle size, pressure, temperature, presence of catalyst
3
Q
What does a catalyst do?
A
It provides an alternative pathway with lower activation energy
4
Q
Template to explain how factors affect the rate of reaction
A
_______–> Increases chance of collision –> Increases frequency of effective collision –> Increases rate of reaction
