Understanding the van der Waals Equation
The van der Waals equation accounts for the non-ideal behavior of real gases by introducing two constants: 'a' and 'b'. These constants correct for intermolecular forces and the volume occupied by gas molecules, respectively.
Option A: Ideal Behavior at Large Molar Volumes
- Real gases behave like ideal gases at large molar volumes.
- At high volumes, the intermolecular forces become negligible, and the volume of the gas molecules is insignificant compared to the total volume.
- Thus, the gas follows the ideal gas law closely.
Option C: Dependence of van der Waals Coefficients
- The coefficients 'a' and 'b' are specific to each gas and represent intrinsic properties such as molecular size and attraction.
- These coefficients are independent of temperature, as they reflect the physical characteristics of the gas itself.
- Thus, the identity of the gas determines these values, but temperature does not affect them directly.
Option D: Pressure Comparison with Ideal Gas
- The pressure exerted by a van der Waals gas is lower than that predicted by the ideal gas law under the same conditions.
- This is due to the attractive forces between gas molecules, which reduce the effective pressure exerted on the walls of the container.
- Therefore, real gases, as described by the van der Waals equation, experience lower pressure than ideal gases under similar circumstances.
Conclusion
The options A, C, and D accurately describe the behavior of gases according to the van der Waals equation, highlighting the differences between real and ideal gases. Understanding these principles is crucial for grasping concepts in thermodynamics and physical chemistry.
