Big Idea 4: Rates of chemical reactions are determined by details of the molecular collisions. (Kinetics)
Enduring Understandings
- 4.A: Reaction rates that depend on temperature and other environmental factors are determined by measuring changes in concentrations of reactants or products over time.
- 4.B: Elementary reactions are mediated by collisions between molecules. Only collisions having sufficient energy and proper relative orientation of reactants lead to products.
- 4.C: Many reactions proceed via a series of elementary reactions.
- 4.D: Reaction rates may be increased by the presence of a catalyst.
