Kinetics II

Question 1

Define enthalpy of atomisation

Answer 1

• energy transferred when 1 mole of the compound is formed from its elements under standard conditions and standard states of all reactants and products.

Question 2

Define enthalpy of atomisation.

Answer 2

• enthalpy change when 1 mole of GASEOUS atoms is formed from the element in standard states.

Question 3

Define 1st ionisation enthalpy

Answer 3

• enthalpy change required to remove 1 mole of electrons from 1 mole of gaseous atoms to form one mole of gaseous ion with a 1+ charge.

Question 4

Define 2nd ionisation enthalpy

Answer 4

enthalpy change required to remove 1 mole of electrons from 1 mole of gaseous atoms to form one mole of gaseous ion of a 1+ to a 2+ charge.

Question 5

Define first electron affinity

Answer 5

enthalpy chanhe that occurs when 1 mole of gaseous atoms gain 1 mol of electrons to form 1 mol of gaseous atoms with a 1- charge.
