Standard enthalpy changes
Cards in this deck (9)
- 1Standard conditions1 atmosphere and 298K
- 2Standard enthalpy change of reactionThe enthalpy change that accompanies a reaction in the molar quantities expressed in a chemical equation under standard conditions, all reactants and products being in their standard states
- 3Standard enthalpy change of combustionThe enthalpy change that takes place when 1 mole of a substance reacts completely with oxygen under standard conditions, all reactants and products being in their standard states
- 4Standard enthalpy change of formationThe enthalpy change that takes place when 1 mole of a compound is formed from its constituent elements in their standard states under standard conditions
- 5Standard stateThe physical state of a substance under standard conditions
- 6Moles(n)=Mass(m) / Molar mass(M)
- 7Bond enthalpyThe enthalpy change that takes place when breaking by homolytic fission 1 mole of a given bond in the molecules of a gaseous species
- 8Average bond enthalpyThe average enthalpy change that takes place when breaking by homolytic fission 1 mole of a given type of bond in the molecules of a gaseous species
- 9Hess' law states thatIf a reaction can take place by more than one route and the initial and final conditions are the same, the total enthalpy change is the same for each route
