Rate of reactions Flashcards
1
Q
How to measure the rate of reaction
A
- Measure time taken for reaction to complete
- Measure volume of gas evolved at regular time intervals
- Measure mass of reaction mixture at regular time intervals
2
Q
What is the collision theory
A
Collision Theory states that a chemical reaction can only occur when the reacting particles collide with each other in the correct orientation and possess activation energy
3
Q
What are the factors affecting the rate of reaction
A
- Particle size
- Concentration
- Pressure (Gases)
- Temperature
- Catalyst
3
Q
What is activation energy
A
Activation energy is the minimum amount of energy that reacting particles must possess for a chemical reaction to occur
4
Q
What affects yield
A
Number of moles of limiting
