Rate of reaction
The change in concentration of a reactant or product per unit time.
1 of 21
Initial rate of reaction
The change in concentration of a reactant, or product, when t=0.
2 of 21
Order
The power to which the concentration of the reactant is raised in the rate equation.
3 of 21
Overall order
Sum of the individual orders.
4 of 21
Half-life
The time taken for the concentration of the reactant to reduce by half.
5 of 21
Rate-determining step
Slowest step in the reaction mechanism.
6 of 21
Intermediate
A species formed in one step of a reaction that is used up in a subsequent step, and is not seen as either a reactant, or a product of the overall equation.
7 of 21
Dynamic equilibrium
Exists in a closed system when the rate of the forward reaction is equal to the rate of the reverse reaction.
8 of 21
Homogeneous equilibrium
An equilibrium in which all the species making up the reactants and products are in the same physical state.
9 of 21
Heterogeneous equilibrium
An equilibrium in which all the species making up the reactants and products are in different physical states.
10 of 21
Bronsted-Lowry acid
Proton donor.
11 of 21
Bronsted-Lowry base
Proton acceptor.
12 of 21
Alkali
Base that dissolves in water forming OH- ions.
13 of 21
Neutralisation
A chemical reaction in which an acid and a base react together to produce a salt and water.
14 of 21
Acid-base pair
A pair of two species that transform into each other by gain or loss of a proton.
15 of 21
Strong acid
An acid that completely dissociates in solution.
16 of 21
Weak acid
An acid that partially dissociates in solution.
17 of 21
Buffer solution
A mixture that minimises the change in pH on addition of small amounts of acid or base.
18 of 21
Equivalence point
The point in a titration at which the volume of one solution has reacted exactly with the volume of the second solution.
19 of 21
End point
The point in a titration at which there are equal concentrations of the weak acid and conjugate base form of the indicator.
20 of 21
Enthalpy change of neutralisation
Enthalpy change when solutions of an acid and an alkali react together to produce 1 mole of water under standard conditions.
