rate of reaction Flashcards
1
Q
rate of reaction equation
A
any reaction = change in quantity/time
2
Q
rate of reaction experiment
A
- Hydrochloric acid + sodium thiosulphate causes solution to go cloudy
- Measure time for cross to disappear
- Repeat at different temperatures
3
Q
how to increase rate of reactions
A
- Increase surface area/concentration/pressure
- Increase temperature
- Add a catalyst
4
Q
what happens when you increase temperature
A
particles move faster, collide more frequently & with more energy -> more likely to be successful
