Physical Chemistry

The equation of state of a hypothetical ideal gas.

Relates the pH of a buffer solution to the $pK_a$ and the ratio of conjugate base to acid concentrations.

States that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.

States that the volume of a gas is directly proportional to its absolute temperature at constant pressure.

The vapor pressure of an ideal solution is dependent on the vapor pressure of each chemical component and the mole fraction of that component present in the solution.

The average speed of gas particles as determined by their kinetic energy.

The solubility of a gas in a liquid is proportional to the partial pressure of the gas above the liquid.

An equation of state for real gases that accounts for molecular size and intermolecular forces.

Calculates the relative amounts of products and reactants at any point during a reaction.

An equation that links the initial or forward reaction rate with the concentrations or pressures of the reactants and constant parameters.

Relates the number of degrees of freedom, components, and phases in a system at equilibrium.

The volume occupied by one mole of a substance (gas) at a given temperature and pressure.

The pressure required to stop the flow of solvent through a semipermeable membrane.

Used to calculate the pH of a buffer solution consisting of a weak acid and its conjugate base.
