PRESENTATION OUTLINE
Why Should We Speed Up a Chemical Reaction?
- Manufacturing Purposes
- The product may be necessary
- in an emergency
Why Should We Slow Down a Chemical Reaction?
- In Demonstrations
- For Safety
Factors that Affect Chemical Reactions
- Temperature
- Concentration
- Stirring
- Catalysts
Temperature:
The higher the temperature, the faster the particles move, speeding up the reaction.
Concentration:
The more reactants present, the greater the rate of particles colliding, and the faster the rate of reaction.
Stirring:
Stirring moves the particles around and increases their contact with each other, speeding the reaction.
Catalysts:
A catalyst is a substance that is neither a reactant nor product that changes the environment so the particles move faster, speeding the reaction.
