Example 1
easyList four factors that affect the rate of a chemical reaction and explain how each works.
Solution
- 1 Temperature: higher temperature → faster molecular motion → more frequent and energetic collisions → faster rate.
- 2 Concentration: higher concentration → more reactant particles per volume → more frequent collisions → faster rate.
- 3 Surface area: finer particles → more exposed surface → more collisions per unit time → faster rate.
- 4 Catalyst: lowers activation energy → greater fraction of successful collisions → faster rate.
Answer
All four factors relate to collision theory: reactions occur when particles collide with sufficient energy and proper orientation. Anything that increases effective collisions increases the rate.
