Thermodynamics Definitions Flashcards
What is enthalpy of formation?
The enthalpy change when 1 mole of a compound is formed from its elements in their standard states.
What is the bond dissociation enthalpy?
The enthalpy change when all the bonds of the same type in 1 mile of gaseous molecules are broken.
What is the enthalpy change of atomisation of an element?
The enthalpy change when 1 mile of gaseous atoms is formed from an element in its standard state.
What is enthalpy change of atomisation of a compound?
The enthalpy change when 1 mole of a compound in its standard state is converted to gaseous atoms.
What is the first ionisation energy?
The enthalpy change when 1 mole of gaseous 1+ ions is formed from 1 mole of gaseous atoms.
What is the second ionisation energy?
The enthalpy change when 1 mole of gaseous 2+ ions are formed from 1 mole of gaseous 1+ ions.
What is the first electron affinity?
The enthalpy change when 1 mole of gaseous 1- ions is made from 1 mole of gaseous atoms.
What is the second electron affinity?
The enthalpy change when 1 mole of gaseous 2- ions is made from 1 mole of gaseous 1- ions.
What is the enthalpy of hydration?
The enthalpy change when 1 mole of aqueous ions is formed from gaseous ions.
What is the enthalpy change of solution?
The enthalpy change when 1 mole of an iconic substance dissolves in enough solvent to form an infinity dilute solution.
