C2.4 revision

HideShow resource information
How do you measure the rate of reaction? Give 4 ways.
-Precipitate -Gas Production -Change in mass -Colour Change
1 of 9
Give 4 ways to speed up reactions?
-Catalyst -Surface Area Increase -Temperature increase -Increase Concentration
2 of 9
What is the collision theory?
For a reaction to happen, the particles must collide with enough energy to break the bonds.
3 of 9
What is activation energy?
The energy needed for a chemical reaction to take place.
4 of 9
Fill in the missing word(s): The higher the temperature, the more _____ per second, as the particles have more energy.
Collisions
5 of 9
How do catalysts speed up the rate of reaction?
They weaken the bonds, and lower the activation energy.
6 of 9
In terms of collision theory, what happens to the temperature when you increase it?
The faster the rate of reaction, because the particles are moving faster (more energy) so more collisions take place.
7 of 9
