lattice enthalpy

Question 1

lattice enthalpy

Answer 1

formation of 1mol of ionic lattice from gaseous ions

Question 2

enthalpy change of solution

Answer 2

dissolving of 1 mol of solute

Question 3

enthalpy change of hydration

Answer 3

dissolving of 1 mol of gaseous ions in water

Question 4

route 1 of Born-Haber cycle

Answer 4

formation of gaseous atoms
formation of gaseous ions
lattice formation

Question 5

route 2 of born-haber cycle

Answer 5

coverts elements in their standard state directly to ionic lattice
enthalpy change off formation

Question 6

working out born-haber cycle

Answer 6

route 1 = route 2

Question 7

enthalpy change of formation

Answer 7

1 mol of a compound is formed from its elements under standard conditions, all reactants and products in standard state

Question 8

enthalpy change of atomisation

Answer 8

formation of one mole of gaseous atoms from the element in its standard state under standard conditions
endothermic

Question 9

first ionisation energy

Answer 9

energy required to remove one electron from each atom in one mole of gaseous to from one mole of gaseous 1+

Question 10

first electron affinity

Answer 10

one electron is added to each atom in one mole of gaseous atoms to form one mole of gaseous 1- ions

Question 11

entropy

Answer 11

measure of a the dispersal of energy in a system which is greater, more disordered a system
