Temp, catalyst, concentration, surface area
2
Q
Ways to measure rates of reaction(3)
A
Precipitation and colour change, change in mass, volume of gas given off
3
Q
Describe reversible reactions
A
Reactions that can be reversed back to its original state
4
Q
What is equilibrium
A
When both reactions happen at the same rate
5
Q
How can you change it
A
Temp, pressure, concentration
6
Q
What is le chatelier principle?
A
Whatever you do to a reaction the reaction will try to reverse the change
7
