Carbon dioxide (data page)
Data obtained from CRC Handbook of Chemistry and Physics, 44th ed. page 1463. (4.25 and 14.99 um) Except where noted otherwise, data relate to standard ambient temperature and pressure. Disclaimer applies. .For kPa values, where datum is whole numbers of atmospheres exact kPa values are given, elsewhere 2 significant figures derived from mm Hg data. The table below gives thermodynamic data of liquid CO2 in equilibrium with its vapor at various temperatures. To convert densities to moles/liter, multiply by 22.678 cm3-mole/liter-gram.
MSDS for solid carbon dioxide is available from Pacific Dry Ice, inc. 47.11 J/(mol K) at 146.48 K 2.534 J/(mol K) at 15.52 K 54.55 J/(mol K) at 189.78 K 33.89 J/(mol K) at –75°C 36.33 J/(mol K) at 0°C 36.61 J/(mol K) at 15°C 38.01 J/(mol K) at 100°C 43.81 J/(mol K) at 400°C 50.87 J/(mol K) at 1000°C 56.91 J/(mol K) at 2000°C 53.01 J/(mol K) at 38°C, 2457 kPa 60.01 J/(mol K) at 38°C, 5482 kPa 183.1 J/(mol K) at 38°C, 8653 kPa 1.37 at –75°C 1.310 at 0°C 1.304 at 15°C 1.281 at 100°C 1.235 at 400°C 1.195 at 1000°C 1.171 at 2000°C CO + ½O2 → CO2 K = pK = log10 K pK = 45.0438 at T = 298.16 K pK = 25.0054 at T = 500 K pK = 16.5383 at T = 700 K pK = 11.8409 at T = 900 K pK = 8.8583 at T = 1100 K pK = 6.7989 at T = 1300 K pK = 5.2943 at T = 1500 K Table data obtained from CRC Handbook of Chemistry and Physics 44th ed. Otherwise temperature is equilibrium of vapor over liquid.
Annotation (s) indicates equilibrium temperature of vapor over solid. This page provides supplementary chemical data on carbon dioxide. The handling of this chemical may incur notable safety precautions.
It is highly recommended that you seek the Material Safety Datasheet (MSDS) for this chemical from a reliable source such as SIRI, and follow its directions. To convert heat values to joules per mole values, multiply by 44.095 grams/mole.
Heat content data, heat of vaporization, and entropy values are relative to the liquid state at 0°C temperature and 3483 kPa pressure. pages 2560-2561, except for critical temperature line (31.1°C) and temperatures –30°C and below, which are taken from Lange s Handbook of Chemistry, 10th ed.
