1
Q
Standard enthalpy change of formation:
A
Enthalpy change when one mole of a compound is formed from its elements under standard conditions.
2
Q
Standard enthalpy change of reaction
A
Enthalpy change of a reaction with its molar quantities in the equation under standard conditions.
3
Q
First Ionization Energy
A
Energy required to remove one electron from each atom in one mole of gaseous atoms to form 1 mole of 1+ ions.
4
Q
Second ionization energy
A
Energy required to remove one electron from each 1+ ion in one mole of gaseous atoms to form 1 mole of 2+ ions.
5
Q
