Reaction Flashcards
1
Q
What’s an effective collision?
A
• leads to a chemical reaction ∵ collision w/ correct orientation + sufficient energy to overcome activation energy
2
Q
What happens to molecules at higher temps?
A
- more molecules energy ≥ Ea
- ∴ > proportion of collisions -> reaction -> increase rate
- Collisions = more frequent ∵ faster movement would
3
Q
What does le Chatelier’s principle state ?
A
When a system in equilibrium is subjected to an external change the system readjusts itself to minimise the effect of that change
