Standard enthalpy change of formation: | arrow_right_alt | Enthalpy change when reaction occurs in the molar quantities shown in the chemical equation under standard conditions. |
Standard conditions: | arrow_right_alt | Enthalpy change when 1 mole of a compound is formed from its elements in their standard states under standard conditions. |
Standard enthalpy of neutralisation: | arrow_right_alt | Enthalpy change when 1 mole of a substance is completely burned in oxygen under standard conditions. |
Enthalpy change: | arrow_right_alt | Enthalpy change when an acid and alkali react together under standard conditions to form 1 mole of water. |
energy transferred = | arrow_right_alt | Heat energy change in a reaction at constant pressure (kJmol-1) |
Standard enthalpy of combustion: | arrow_right_alt | 100 kPa, 298 K, 1 moldm −3 concentrations of ions. (Note not 1atm) |
Standard enthalpy change of reaction: | arrow_right_alt | mass x specific heat capacity × temperature change |
