Kinetics Flashcards
(5 cards)
1
Q
How does concentration effect rate
A
Increased concentration increases rate
More particles of reactants
Increased frequency of collisions
More successful collisions
2
Q
How does pressure effect rate
A
If pressure increases rate increases
Particles forced closer together
Increased frequency of successful collisions
3
Q
How does temperature effect rate
A
Temperature increases rate increases
Increased kinetic energy of particles
More frequent successful collisions (greater number with greater energy)
4
Q
How does surface area effect rate
A
Increased surface increases rate
Increased surface available to react
5
Q
How does a catalyst effect rate
A
Do not get used up
Provides alternate reaction pathway with lower activation energy
More successful collisions
