Standard enthalpy change of reaction |
The enthalpy change when the amounts of reactants shown in the equation for the reaction, react under standard conditions to give the products in their standard states. |
|
|
Standard enthalpy change of formation |
The enthalpy change when one mole of a compound is formed from its elements under standard conditions; both compound and elements are in standard states. |
|
|
Standard enthalpy change of combustion |
The enthalpy change when one mole of an element or compound reacts completely with oxygen under standard conditions. |
