Reaction Kinetics: Rate, Collisions & Temperature
Narrated lesson · press play
Why do some reactions flash in an instant and others take years? Learn what rate of reaction means, how collision theory explains the effect of concentration, what activation energy is, and how the Boltzmann distribution lets us explain — properly — why a small rise in temperature speeds a reaction so dramatically.
What you'll learn in this lesson
By the end you should be able to (NSSCAS Chemistry (AS Level) 2.4.1–2.4.2):
- Explain and use the term rate of reaction
- Explain qualitatively, in terms of collisions, the effect of concentration on rate
- Explain and use the term activation energy, with reference to the Boltzmann distribution
- Explain the effect of temperature on rate using the Boltzmann distribution and collision frequency
