Creating Quantum Theory
3 important questions on Creating Quantum Theory
What is a reaction mechanism
Step by step sequence of elementary rxns by which overall chem change occurs, from reactants thru products
What is the collision model?
Particles collide convert KE to PE to form the activated complex
as # of particles required to collide increases, probability of the particles colliding decreases
as # of particles required to collide increases, probability of the particles colliding decreases
Why is it that as # of particles required to collide increases, probability of the particles colliding decreases?
1. All particles have to collide @ same spot in 3D space @ same time
2. All particles require sufficient energy to collide - avg energy of reactant particles must exceed EA* (activated energy)
3. All particles must collide in correct orientation (for a successful collision)
