Chemical Kinetics
Chemical Kinetics Study of how rapidly a reaction will occur. In
addition to speed of reaction, kinetics also deals with the reaction
mechanism (exactly how the reaction occurs)
Factors that affect reaction rate
1. Concentration of reactants – more particles means more frequent “effective” collisions occur
2. Temperature – higher temps, the molecules have more KE, are moving faster and are more likely to collide
3. Catalyst – chemical that speeds up a reaction by changing the reaction mechanism, not consumed in reaction
4. Physical state of reactants – (phase)
5. Surface area (for solids) – greater SA = faster reaction
