Factors Affectinf Rates Of Reaction Flashcards
1
Q
What’s the four things rate of reaction depends on
A
Temperature
Surface area
Concentration
Whether a catalyst is used
2
Q
When temperature increases what happens to the particles
A
The particles move faster
3
Q
What happens when the particles move faster
A
They collide more often
4
Q
Because increasing temperature leads to having more energy what happens
A
More collisions have enough energy to make the reaction happen
5
Q
What happens if the solution is more concentrated
A
It has more particles
6
Q
When the gas of concentration increases what happens
A
The same number of particles are in a smaller space
7
Q
What happens if they are in a smaller space
A
Collisions between the reactant particles are more frequent
8
Q
What is a catalyst
A
A substance that speeds up a reaction
