Edexcel IAL Chemistry AS 9.1 Collision theory and rate factors
Identify which factor changed, state its particle-level effect and link that change to more or fewer successful collisions per unit time without altering final yield unless…
How this is tested
- Explain concentration or pressure effects through particles per volume and collision frequency.
- Explain surface-area effects through more exposed particles and collision opportunities.
- Separate a faster initial rate from unchanged final product when reacting amounts are fixed.
