Reaction

Question 1

What’s an effective collision?

Answer 1

• leads to a chemical reaction ∵ collision w/ correct orientation + sufficient energy to overcome activation energy

Question 2

What happens to molecules at higher temps?

Answer 2

• more molecules energy ≥ Ea
• ∴ > proportion of collisions -> reaction -> increase rate
• Collisions = more frequent ∵ faster movement would

Question 3

What does le Chatelier’s principle state ?

Answer 3

When a system in equilibrium is subjected to an external change the system readjusts itself to minimise the effect of that change
