Born hater cycles - key definitions

Question 1

Enthalpy of solution

Answer 1

The enthalpy change when one mole of a compound is dissolved to form an infinitely dilute solution.

Question 2

Enthalpy of hydration

Answer 2

Enthalpy change when one mole of gaseous ions is dissolved in water to form an infinitely dilute solution.

Question 3

Lattice enthalpy

Answer 3

Enthalpy change that accompanies the formation of 1 mole of ionic lattice from its gaseous ions.

Question 4

Enthalpy of formation

Answer 4

Enthalpy change when one mole of a compound is formed from its elements, under standard conditions with all reactants and products in their standard states

Question 5

1st ionisation energy

Answer 5

the energy required to remove one electron from each atom in one mole of gaseous atoms of an element to form one mole of gaseous 1+ ions

Question 6

Enthalpy of atomisation

Answer 6

The enthalpy change for formation of 1 mole of gaseous atoms from the element in its standard state and under standard conditions.

Question 7

1st electron affinity

Answer 7

The energy change when one mole of electrons is added to gaseous atoms to form one mole of gaseous 1- ions
