Rates of reactions Flashcards
1
Q
What is activation energy?
A
The least amount of energy required to activate atoms or molecules to a state in which they can undergo a chemical reaction.
2
Q
What is the collision theory?
A
In order for a reaction to take place, particles must:
- collide
- have correct orientation
- have sufficient energy for reaction to occur
3
Q
How can the rate of a reaction be measured?
A
- volume of gas evolved
- mass of solid formed
- decrease in mass due to evolved gas
- intensity of colour of solution
- formation of precipitate
- pH
- temperature
4
Q
What is the Maxwell- Boltzmann distribution curve?
A
A statistical analysis of the range of energies present in particles of a gas sample.
Explains factors that influence chemical reactions and rates.
