Big idea: why concentration and pressure affect rate

Big idea: why concentration and pressure affect rate

Particle diagrams showing low and high concentration in solution and low and high pressure in gases, with higher collision frequency labelled in the crowded cases

For a reaction to happen, particles must collide with enough energy to overcome the activation energy, and they must collide with a suitable orientation. The rate depends on how many successful collisions happen each second.

  3. /Effect of concentration and pressure

Step-by-step lessons on AQA A Level Chemistry Effect of concentration and pressure. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
