Fugacity is a corrected pressure that:
Fugacity is a corrected pressure that:
Show Hint
Fugacity provides a correction for the non-ideal behavior of gases, allowing the ideal gas law to be applied more accurately in real-world scenarios.

- Replaces pressure in ideal gas equations
- Applies to solids only
- Equals actual pressure
- Increases with ideality

The Correct Option is A
Solution and Explanation
Fugacity is a concept used in thermodynamics to describe the "effective pressure" exerted by a real gas, which replaces the actual pressure in the ideal gas equation when dealing with non-ideal behavior. The idea behind fugacity is to adjust the ideal gas law to account for deviations from ideal behavior, such as intermolecular forces and volume exclusion. Fugacity is used in place of pressure in the calculations involving real gases to make the calculations more accurate.
Thus, the correct statement is that fugacity replaces pressure in ideal gas equations when dealing with real gases.
Thus, the correct statement is that fugacity replaces pressure in ideal gas equations when dealing with real gases.
