Standard entropies for substances are defined at a pressure of exactly 1 bar or exactly 1 atm in different books. For gases, this correction factor would be..... in J/molK?
Answer is in format 0.xxxxxx
I'm a little confused... I'd appreciate any help.
1 atm= 1.013 25 bar or
1 bar= 0.986923 atm
Is that what it means by correction factor?
The answers you provided were not in J/mol*K... instead they were just conversions... is that what the question is asking?
The question above further asked if this would apply to solids and liquids, and the answer is 'no'.
I apologize for any confusion. The correction factor you mentioned does not directly apply to the standard entropy of gases. The correction factor you mentioned is for converting between different pressure units (atm and bar).
The standard entropy for a substance at a given temperature and pressure is typically reported in units of J/mol*K. However, the question seems to be asking for a correction factor specific to gases.
In the case of gases, the correction factor you are asking about is related to the difference between the ideal gas approximation and real gas behavior. The ideal gas law assumes that gases behave infinitely well, with no intermolecular forces or volume occupied by the gas particles themselves. In reality, gases deviate slightly from this ideal behavior at high pressures or low temperatures.
To correct for this deviation, one approach is to use the compressibility factor (Z), which is the ratio of the observed pressure to the pressure calculated using the ideal gas law. The compressibility factor can be used to correct the standard entropy of a gas. However, this correction factor can vary depending on the particular gas and its conditions.
Unfortunately, without specific information about the gas in question, it is not possible to provide a general correction factor for all gases. Additionally, the correction factor is usually not presented as a single decimal value like 0.xxxxxx. It would typically be calculated using thermodynamic data or equation of state models.
Regarding solids and liquids, the standard entropy values for these phases are typically reported at a given temperature and pressure. They do not require the same correction factor as gases because their behavior is different due to intermolecular forces and other factors.
