Notes

  • All values refer to 25 °C and to the thermodynamically stable standard state at that temperature unless noted.
  • Values from CRC refer to "100 kPa (1 bar or 0.987 standard atmospheres)". Lange indirectly defines the values to be standard atmosphere of "1 atm (101325 Pa)", although citing the same NBS and JANAF sources among others. It is assumed this inexactly refers to "ambient pressure".
