Join award-winning science educator Dr David Boyce as we break down the Boltzmann distribution and its crucial role in understanding reaction rates.
In this video, you’ll explore how the energy of particles is distributed at a given temperature, and why only a fraction have enough energy to react. We then apply this to rates of reaction, showing clearly how increasing temperature changes the distribution and increases the number of successful collisions.
You’ll also see how activation energy fits into the curve, and how to interpret it visually. Finally, we explain how a catalyst works in terms of the Boltzmann distribution — lowering the activation energy and allowing more particles to react without changing the overall distribution.
📈 Clear diagrams, detailed explanations, and exam-focused insight — everything you need to confidently tackle this key A Level topic.
