Rates Of Reaction Flashcards
0
Q
Increase in concentration =
A
Increase in rate BECAUSE
• more particles in a given volume that collide more often
1
Q
Factors affecting rate of reaction
A
- concentration of reactant
- temperature of reaction
- surface area of a reactant
- pressure
2
Q
Increase in temperature
A
Increase in rate BECAUSE
• particles have more energy so more collisions have required activation energy
3
Q
Increase in surface area
A
Increase in rate BECAUSE
• more particles in contact with the other reactant and so they collide more often
4
Q
Increase in pressure
A
Increase in rate in gases BECAUSE
• increase in pressure means that particles hit each other more frequently
5
Q
Dynamic equilibrium has which features?
A
- rate of forward reaction = rate of backward reaction
- amounts of reactants and products remain constant
- any property which depends on amounts of reactants and products remain the same (i.e colour or pressure)
