Lattic Energy Flashcards
1
Q
Enthalpy change
A
Amount of heat energy transferred during a chemical reaction, at a constant pressure
2
Q
Enthalpy of atomisation
A
When one mole of gaseous atom is formed from its element under standard condition
Eg: Na (s) —> Na (g)
3
Q
What are the standard conditions
A
Temperature: 298 k
Pressure: 101 kPa
4
Q
Lattice energy
A
When one mole of an ionic compound is formed from one mole of gaseous ions under standard conditions
5
Q
First Electron affinity
A
Enthalpy change when one mole of electrons is added to one mole of gaseous atoms to form one mole of negative gaseous ions under standard conditions.
