Module 3 NTR definitions Flashcards
What is second ionisation energy?
The energy required to remove one electron from each 1+ ion in one mole of gaseous 1+ ions to form one mole of gaseous 2+ ions
What is successive ionisation energy?
A measure of the energy required to remove each electron in turn
What is enthalpy change?
The amount of heat released/absorbed by a chemical reaction, carried out at a constant pressure in kJ/mol
What is standard enthalpy change of reaction?
The enthalpy change that accompanies a reaction in molar quantities expressed in a chemical equation under standard conditions, all reactants and products being in their standard states
What is Hess’ Law?
The enthalpy change of a reaction depends only on the initial and final states and is independent of the route taken
What is Kc expression?
