The Rate & Extent of Chemical Change Flashcards
1
Q
What is the equation for Rate of Reaction
A
Rate of Reaction = Quantity of Products
formed or Reactants used / Time
2
Q
Name 4 factors affecting the rate of reaction
A
1) Temperature
2) Concentration
3) Surface Area
4) Catalyst
3
Q
What is the collision theory
A
For particles to react, they must collide with a certain amount of energy
(activation energy)
4
Q
What happens in an endothermic reaction?
A
Heat energy is taken in from the surroundings so temperature decreases
5
Q
What happens in an exothermic reaction?
A
Heat energy is released to the surroundings so temperature increases
6
Q
What are the three factors that affect the position of equilibrium?
A
Temperature
Concentration
Pressure
