Intermolecular Forces in Solutions02:28

Intermolecular Forces in Solutions

40.6K
The formation of a solution is an example of a spontaneous process, a process that occurs under specified conditions without energy from some external source.
When the strengths of the intermolecular forces of attraction between solute and solvent species in a solution are no different than those present in the separated components, the solution is formed with no accompanying energy change. Such a solution is called an ideal solution. A mixture of ideal gases (or gases such as helium and argon,...

Real Gases: Effects of Intermolecular Forces and Molecular Volume Deriving Van der Waals Equation

39.8K
Thus far, the ideal gas law, PV = nRT, has been applied to a variety of different types of problems, ranging from reaction stoichiometry and empirical and molecular formula problems to determining the density and molar mass of a gas. However, the behavior of a gas is often non-ideal, meaning that the observed relationships between its pressure, volume, and temperature are not accurately described by the gas laws.

Intermolecular Forces03:13

Intermolecular Forces

75.5K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Surface Tension of Fluid01:22

Surface Tension of Fluid

1.8K
Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension.
Surface tension varies...

Comparing Intermolecular Forces: Melting Point, Boiling Point, and Miscibility

52.8K
Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, and solubilities (miscibilities) of substances. Molar mass, molecular shape, and polarity affect the strength of different intermolecular forces, which influence the magnitude of physical properties across a family of molecules.
Temporary attractive forces like dispersion are present in all molecules, whether they are polar or nonpolar. They...

Area of Science:

  • Physical Chemistry
  • Computational Chemistry
  • Geochemistry

Background:

  • Interfacial tension (IFT) between fluids and solids is critical for industrial and natural processes, including geological CO2 storage.
  • Existing experimental data on CO2-water IFT under supercritical conditions are limited and sometimes conflicting.
  • Molecular modeling offers a complementary approach to experimental IFT determination, especially under challenging conditions.

Purpose of the Study:

  • To predict the interfacial tension (IFT) of the carbon dioxide-water system using computational methods.
  • To investigate the influence of pressure, temperature, and salinity on CO2-water IFT.
  • To provide a reliable and efficient computational tool for IFT prediction in CO2 storage applications.

Main Methods:

  • Density Functional Theory (DFT) calculations were employed.
  • The COSMO-RS implicit solvent model was integrated with DFT.
  • IFT was predicted across a range of pressures (0-50 MPa), temperatures (273-383 K), and NaCl salinities (0-5 M).

Main Results:

  • The predicted CO2-water IFT values show good agreement with existing experimental data and molecular dynamics simulations.
  • The model successfully captures the dependence of IFT on pressure, temperature, and salinity.
  • The computational approach demonstrates accuracy within the uncertainty margins of experimental and simulation data.

Conclusions:

  • The combination of DFT and COSMO-RS provides a fast and accurate method for predicting CO2-water IFT.
  • This model serves as a valuable alternative to time-consuming experimental measurements and complex simulations.
  • The findings support the application of this method for understanding CO2 behavior in geological storage.
