Rate Of Reaction Flashcards
(4 cards)
1
Q
What is rate of reaction?
A
Rate of reaction is how fast a chemical reaction happens
2
Q
Concentration of reactants
A
Increasing the concentration means there are more particles in the same space
More particles = more frequent collisions so the reaction happens faster
3
Q
Surface area
A
Breaking a solid into smaller pieces increases its surface area
More particles are exposed to react so they collide more, this speeds up the reaction
Smaller pieces = more particles exposed = faster reaction
4
Q
Temperature
A
Increasing temperature gives particles more energy
Particles move faster and collide more often
And with energy, more successful collisions, so the reaction is faster
