Rate of reaction
Flashcards do conjunto (7)
- 1What affects the rate of reaction?Temperature, concentration, particle size and the use of a catalyst.
- 2What is a catalyst?A catalyst increases the rate of reaction, but is not used up in it.
- 3What is the formula for calculating the rate of reaction?rate = change in volume/change in time
- 4Why would a catalyst be used in industry?It allows the reaction to be preformed at a lower temperature, saving energy and money.
- 5How does temperature affect the rate of reaction?The higher the temperature, the faster the reaction.
The lower the temperature, the slower the reaction. - 6How does concentration affect the rate of reaction?The higher the concentration, the faster the reaction.
The lower the concentration, the slower the reaction. - 7How does particle size affect the rate of reaction?The smaller the particle, the faster the reaction.
The bigger the particle, the slower the reaction.
