Rates of reaction Flashcards
1
Q
What is the link between rate of reaction and concentration?
A
Decrease the concentration of reactant, the rate of reaction goes slower
2
Q
What is the relationshiop between rate of reaction and temperature?
A
Increase the temperature increase the rate of reaction
3
Q
What the relationship between particle size, surface area and rate of reaction?
A
If particle size is reduced the surface area increases, and the rate of reaction increase
4
Q
What is a catalyst?
A
It is a chemical that speed up the rate of reaction without been used up.
5
Q
How to calculate the rate of reaction?
A
Difference in quantity divided by the difference in time
