Standard Reactions
Cards in this deck (5)
- 1Define the standard enthalpy change of combustion.The enthalpy change that occurs when one mole of a substance is burnt completely in oxygen under standard conditions in standard states.
- 2Define the standard enthalpy change of formation.The enthalpy change when one mole of a compound is formed from its elements under standard conditions in standard states.
- 3Define the standard enthalpy change of neutralisation.The enthalpy change when one mole of hydrogen ions react with one mole of hydroxide ions to form one mole of water under standard conditions and in solution containing 1mold dm^-3
- 4Define standard conditions.Temperature: 298K
Pressure: 1atm
Concentration: 1mol dm^-3 - 5Define the standard enthalpy change of a reaction.The enthalpy change when molar quantities of reactants as stated in the equation react together under standard conditions.
