thermodynamics

Question 1

what is the definition of enthalpy of 2nd electron affinity

Answer 1

the standard enthalpy change when one mole of electrons is added to a mole of gaseous ions, each with a single negative charge, to form a mole of ions each with 2- charge

Question 2

what is the definition of enthalpy of first ionisation

Answer 2

the standard enthalpy change when one mole of electrons is removed from one mole of gaseous atoms to give one mole of gaseous ions each with a single positive charge

Question 3

what is the definition of 2nd ionisation enthalpy

Answer 3

the standard enthalpy change when one mole of electrons is removed from one mole of gaseous 1+ ions to give one mole of gaseous ions each to give one mole of gaseous ions each with 2+ charge

Question 4

what is the definition of lattice dissociation

Answer 4

the standard enthalpy change when one mole of a compound dissociates into its gaseous ions

Question 5

what is the definition of first electron affinity

Answer 5

the standard enthalpy change when one mole of gaseous atoms is converted into a mole of gaseous ions each with a single negative charge under standard conditions.

Question 6

Define standard enthalpy of solution

Answer 6

The standard enthalpy change when one mole of solute dissolves to form it’s aqueous ions
