Rate Of Reaction Flashcards
1
Q
Particle size
A
Smaller particle size means larger total surface area
Higher frequency of EFFECTIVE collision
2
Q
Temperature
A
Higher temperature has more kinetic energy
Higher frequency of EFFECTIVE collision
Rate of reaction increases
3
Q
Concentration
A
Higher concentration means more reactant particles PER UNIT VOLUME
Higher frequency of effective collision
Rate of reaction increases
4
Q
Pressure
A
(GAS ONLY)
Higher pressure means more reactant particles PER UNIT VOLUME
Higher frequency of effective collision
Rate of reaction increases
5
Q
Exothermic Reaction
A
during the reaction, heat is released into the surroundings
6
Q
Endothermic reaction
A
during the reaction, heat from the surrounding is absorbed and this the temperature decreases
