Lessons

Rate of reaction and collision theoryWhat rate means, why only some collisions work, and why concentration and pressure change how fast a reaction goes. 6 min, not started
Concentration and pressure: more collisions, more chancesExplain why increasing concentration or gas pressure usually increases reaction rate through more frequent effective collisions. 4 min, not started
Calculating reaction rate from dataTurn concentration, mass, gas-volume or time data into an average reaction rate with sensible units. 4 min, not started
Reaction rate: counting useful collisionsLearn what reaction rate means and why only effective collisions make reactants turn into products. 4 min, not started
Measuring and calculating rateFollow a reaction by gas volume, mass loss or colour, then find the rate from data or from the gradient of a curve. 6 min, not started
