Reaction Kinetics Flashcards
What is the standard enthalpy change in atomisation?
The standard enthalpy change of atomisation of an element is the enthalpy change when one mole of gaseous atoms is formed from the element in its standard state under standard conditions.
What is the standard enthalpy change in formation?
The standard enthalpy change of formation of a substance is the enthalpy change which occurs when one mole of a substance is formed from its constituent elements in their standard state under standard conditions.
What is the standard enthalpy change in combustion?
The standard enthalpy change of combustion of a substance is the enthalpy change when one mole of the substance is completely burnt in oxygen under standard conditions.
What is ionisation energy (1st and 2nd)
The first ionisation energy of an element is the enthalpy change when one mole of electrons is removed from one mole of gaseous atoms
The second ionisation energy of an element is the enthalpy change when one mole of electrons is removed from one mole of gaseous, single charged cations of the element.
What is electron affinity (1st and 2nd)
The first electron affinity of an element is the enthalpy change when one mole of gaseous atoms accepts one mole of electrons.
The second electron affinity of an element is the enthalpy change when one mole of gaseous, singled charged negative atoms accept one mole of electrons.
What is lattice energy?
Lattice energy is the enthalpy change when one mole of the solid ionic compound is formed from its constituent gaseous ions under standard conditions.
What is the bond disassociation energy?
Bond disassociation energy is the average enthalpy change when one mole of covalent bonds between atoms in gaseous molecules is broken.
What is the standard enthalpy change of neutralisation?
The standard enthalpy change of neutralisation is the enthalpy change when one mole of water is formed from the reaction of an acid and an alkali under standard conditions.
What is the standard enthalpy change of hydration?
The standard enthalpy change of hydration is the enthalpy change when one mole of gaseous ions is hydrated under standard conditions.
What is the standard enthalpy change of solution?
The standard enthalpy change of solution is the enthalpy change when one mole of the substance dissolves completedly to give an infinitely dilute solution under standard conditions so that no further enthalpy change takes place on adding more solvent.
