rate of reaction p2 Flashcards
1
Q
how to find mean rate of reaction?
A
mror= amount of reactant or product formed/ time taken
2
Q
how can rate of reaction be found?
A
measuring the amount of reactant used e.g gas would be measured in grams
3
Q
what do you do to find the total volume of a gas?
A
use a gas syringe
4
Q
what is collision theory?
A
chemical reactions that only occur when reacting particles collide with each other with sufficient energy
5
Q
what is the minimum amount of energy required to cause a reaction?
A
activation energy
6
Q
what factors affect rate of reaction?
A
temperature and concentration
7
Q
what is the required practical for this subjecT?
A
adding hydrochlauric acid to a flask and swirling and timing until the cross aint visibl,e no more
