THE CHANGE IN CONCENTRATION OF A REACTANT OR PRODUCT PER UNIT TIME
1 of 31
ORDER (OF A REACTANT)
POWER TO WHICH THE CONCENTRATION OF THE REACTANT IS RAISED IN THE RATE EQUATION
2 of 31
RATE CONSTANT, k
THE CONSTANT THAT LINKS THE RATE OF REACTION WITH THE CONCENTRATION OF THE REACTANTS RAISED TO THE POWERS OF THEIR ORDERS IN THE RATE EQUATION
3 of 31
RATE EQUATION
FOR REACTION A+B -> C, rate=k[A]^m[B]^n (where m and n are the orders of the reactants)
4 of 31
OVERALL ORDER
SUM OF THE INDIVIDUAL ORDERS
5 of 31
HALF-LIFE
TIME TAKEN FOR THE CONCENTRATION OF THE REACTANT TO REDUCE BY HALF
6 of 31
REACTION MECHANISM
SERIES OF STEPS THAT, TOGETHER, MAKE UP THE OVERALL REACTION
7 of 31
RATE-DETERMINING STEP
SLOWEST STEP IN THE REACTION MECHANISM OF A MULTI-STEP REACTION
8 of 31
INTERMEDIATE
SPECIES FORMED IN ONE STEP OF A MULTI-STEP REACTION, THAT IS USED UP IN A SUBSEQUENT STEP, AND IS NOT SEEN AS EITHER A REACTANT OR PRODUCT OF THE OVERALL EQUATION

EQUILIBRIUM LAW
STATES THAT FOR THE EQUILIBRIUM aA + bB -> cC + dD, Kc = [C]^c[D]^d/[A]^a[B]^b
11 of 31
HOMOGENEOUS EQUILIBRIUM
EQUILIBRIUM WHERE ALL THE SPECIES MAKING UP THE REACTANTS AND PRODUCTS ARE IN THE SAME PHYSICAL STATE
12 of 31
HETEROGENEOUS EQUILIBRIUM
EQUILIBRIUM WHERE ALL SPECIES MAKING UP THE REACTANTS AND PRODUCTS ARE IN DIFFERENT PHYSICAL STATES
13 of 31
MOLE FRACTION
NUMBER OF MOLES OF A / TOTAL MOLES OF ALL SUBSTANCES
14 of 31

19 of 31
NEUTRALISATION
CHEMICAL REACTION IN WHICH AN ACID AND BASE REACT TOGETHER TO PRODUCE A SALT AND WATER
20 of 31
STRONG ACID
ACID THAT COMPLETELY DISSOCIATES IN SOLUTION
21 of 31
WEAK ACID
ACID THAT PARTIALLY DISSOCIATES IN SOLUTION
22 of 31
ACID DISSOCIATION CONSTANT, Ka

28 of 31
BUFFER SOLUTION
MIXTURE THAT MINIMISES pH CHANGES ON ADDITION OF SMALL AMOUNTS OF ACID OR BASE
29 of 31
EQUIVALENCE POINT
POINT IN A TITRATION AT WHICH THE VOLUME OF ONE SOLUTION HAS REACTED EXACTLY WITH THE VOLUME OF THE SECOND SOLUTION - THIS MATCHES THE STOICHIOMETRY OF THE REACTION TAKING PLACE
30 of 31
END POINT
POINT IN A TITRATION AT WHICH THERE ARE EQUAL CONCENTRATIONS OF THE WEAK ACID AND CONJUGATE BASE FORMS OF THE INDICATOR
