What is the ionic product of water?
What is the standard enthalpy
change of solution ΔHsolnθ ?
The enthalpy change that takes place when one mole of a compound is completely dissolved in water under standard conditions.
The quantitative measure of the degree of disorder in a system.
What is Kc for the equilibreum:
aA +bB ⇌ cC + dD
Define half life.
The time taken for the concentration of a reactant to reduce by half.
What is the energy required to remove one electron from each atom in one mole of gaseous atoms to form one mole of gaseous 1+ ions?
First ionisation energy.
What is the energy required
to remove one electron from each ion in one mole of gaseous 1+ ions to form one mole of gaseous 2+ ions?
Second ionisation energy.
What principle states that when a system in dynamic equilibrium is subjected to change, the system readjusts itself to minimize the effect of the change and to restore equilibrium?
Le Chatelier's Principle
What is standard lattice enthalpy? ΔHlattθ
The enthalpy change that accompanies the formation of one mole of an ionic compound from its gaseous ions under standard conditions.
What is the rate equation for the reaction:
A + B → C
- m is the order of reaction with respect to A
- n is the order of reaction with respect to Bm+n = overall order of the reaction
What is standard electrode potential?
The e.m.f. (electromotive force) of a half cell compared with a standard hydrogen half cell, taken under standard conditions.
What are standard conditions?
- 298K or 25°C
- 1 mole dm-3100 kPa or 1 atmosphere
What is the standard enthalpy change of hydration?
The enthalpy change that takes place when one mole of isolated gaseous ions is dissolved in water forming one mole of aqueous ions under standard conditions.
