Coagulation CE 547. Overview Turbidity in surface waters is caused by colloidal clay particles. Color in water is caused by colloidal forms of Fe, Mn,
Kinetics HL and SL 2 6.2 Collision Theory For a reaction to occur 1.particles must collide 2.with enough energy 3.in the correct orientation Not all.
Thermochemistry and Kinetics. Kinetics The branch of chemistry that is concerned with reaction rates and reaction mechanisms Reaction rate:Reaction rate:
Factors Affecting Reaction Rates presence/absence of a catalyst. surface area (particle size) concentration or pressure of a reactant temperature nature.

2 H 2 + O 2 → 2 H 2 O
UNIT I Collision Theory. C OLLISION T HEORY explains rates on the molecular level Basic Premise: before molecules can react, they must collide .
1 Rates of Reaction. 2 Reaction Rates Chemical reactions require varying lengths of time for completion. –This reaction rate depends on the characteristics.
