Chem 4 Flashcards
Overall order of the reaction
The sum of the orders of all the individual species in the rate equation
Rate constant
The rate equation when the concentration of each of the species on the rate equation equals one
Rate determining step
The slowest step in the sequence of steps that forms the mechanism for a reaction
Order with respect to reactant A
The power to which [A] is raised in the rate equation
Acid
A proton donor
Base
Proton acceptor
Strong acid
A species which fully dissociates and solution to give H+ ions
Weak acid
A species which partially dissociates in solution to give H+ ions
Strong base
A species which completely dissociates in solution to give OH- ions
Buffer
A solution which can resist a large pH change on addition of small amounts of acid or alkali
Chiral
And atom attached to 4 different groups
Enantiomers
Molecules which are non-superimposable mirror images of each other
Optical activity
The ability to rotate the plane of plane polarised light
Racemate
An equimolar mixture of two optical isomers
