Calculators

Calculates the pressure, volume, temperature, or number of moles of a real gas using the van der Waals equation of state.

Calculates the root-mean-square (RMS) speed of gas molecules based on temperature and molar mass.

Calculates the quantum yield of a photochemical process, which represents the efficiency of photon usage in initiating a specific reaction. It's the number of times a specific event occurs per photon absorbed.

Calculates the partial pressure of a gas in a mixture using Dalton's Law of Partial Pressures.

Calculates the osmotic pressure of a solution using the van't Hoff equation. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.

Calculates the fractional surface coverage (θ) based on the Langmuir adsorption isotherm model, which describes the equilibrium between adsorption and desorption of a gas on a solid surface.

Calculates the remaining amount of a substance after a certain period, given its initial amount and half-life.

Calculates the relative rate of effusion of two gases using Graham's Law, which states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass.

Calculates the lattice energy of an ionic compound using a simplified Born-Landé equation. This calculator provides an estimate of the energy required to separate one mole of a solid ionic compound into gaseous ions.

Calculates the reduction potential of an electrochemical cell using the Nernst Equation. This equation relates the reduction potential of an electrochemical reaction to the standard electrode potential, temperature, and activities of the chemical species undergoing reduction and oxidation.
