Collision Theory and Reaction Rates

Collision Theory and Reaction Rates. The Collision Theory is a theory which states how reacting particles (like atoms and molecules) must interact to start a chemical reaction. The Collision Theory States 3 Things:. 1 st : Reactant particles must collide in order for the reaction to occur.

Reaction Spontaneity

Reaction Spontaneity. How can a fire start on its own? (without a spark). Spontaneous Reaction. Occurs naturally and favors formation of products 4Fe(s) + 3O 2 (g) ? 2Fe 2 O 3 (s) ?H = -1625 kJ CH 4 (g) + 2O 2 (g) ? CO 2 (g) + 2H 2 O(l) ?H = -891 kJ. Nonspontaneous Reaction.

Potential Energy Diagrams

Potential Energy Diagrams. Chemical Kinetics Mrs. Kay. Review of Exothermic. Reactants Ep is higher than Products Ep. Now, we must consider the activation energy (the energy needed so that the reactants bonds will break and reform to make product). Review of Endothermic.
