5.3 Flashcards
1
Q
Rate of Reaction
A
The speed at which a chemical reaction proceeds.
2
Q
Temperature
A
Increasing it increases rate of reaction because it speeds up rate of particles in liquids and gases-colliding more
3
Q
Concentration
A
Amount of reactants present in volume of liquid or gas during chemical reaction meaning solution is concentrated.
Collide more
4
Q
Agitation
A
(Stirring) ensure reactants are kept in contact by removing build up products around reactants.
5
Q
Surface Area
A
Solids have slower rate of reaction, better when it is in smaller pieces like powder.
6
Q
Catalysts
A
Chemical that helps speed up chemical reactions but not used during the Reaction
7
Q
Enzymes
A
A natural occurring catalyst.
