Kinetics Definitions

3. Provides an alternative reaction route for a reaction to occur, that requires a lower activation energy
5. Rate ___________ : Relates the rate of a chemical reaction at a given temperature to the product of the concentrations of reactants.
7. Method used to calculate the concentration of a specific coloured compound in a solution by measuring the extent to which it absorbs certain wavelengths of light.
8. The time taken for the initial concentration of the reactants to decrease by half.
11. ___________ catalysts: Catalysts that are in a different phase or state to the species in the reaction.
12. An organic compound containing a halogen atom attached to an alkyl chain.

1. ___________ catalysts: Catalysts that are in the same phase or state as the species in the reaction.
2. ___________ energy: The minimum energy required for a reaction to occur.
4. a nucleophilic substitution reaction, where the rate equation involved 2 species.
6. An electron pair donor.
9. Rate ___________ : Describes the relationship between the rate of chemical reaction and the concentrations of reagents.
10. a nucleophilic substitution reaction, where the rate equation involved 1 species.
