1
Q
What factors affect how fast reactions occur?
A
- Physical states of reactants
(solids react slower than liquids & gases) - Concentration of reactants
(more frequent collisions) - Temperature
(more frequent collisions) - Surface area of a substance
(larger surface area = more frequent collisions) - Catalysts
(lower activation energy required)
2
Q
What is “Rate of Change”?
A
A measure of how rapidly a change takes place
3
Q
What is “Rate of Appearance”?
A
A measure of how rapidly a product is produced
4
Q
What is “Rate of Disappearance”?
A
A measure of how rapidly a reactant is used up
5
Q
What is “Rate of Reaction”?
A
A measure of how rapidly a reaction occurs
6
Q
Can partial pressure be used as a measure of concentration?
A
YES!
