Collision Theory
Discover that altering the number of successful collisions between particles is key to changing the rate of chemical reactions. How this can be manipulated? Chemistry - ReactionsLearning Points. New substances are made when particles collide in chemical reactions. The rate of a reaction depends on temperature, pressure, concentration and catalysts. Catalysts speed up reactions by lowering the activation energy. The activation energy is the minimum amount of energy needed to cause a reaction. A Twig Curriculum Film. Delivering key learning points. Get straight to the facts in just three minutes – directly linked to core learning, Twig's curriculum films will fit neatly into your lesson plans.
