Calculators

Calculates the equilibrium constant (Kc) for a reversible chemical reaction based on the concentrations of reactants and products at equilibrium.

Calculates the carbon equivalent (CE) of steel, which indicates its weldability and other properties based on its chemical composition.

Convert moles of a substance to its mass using the molar mass of the substance.

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.

This calculator applies the combined gas law to determine the final pressure, volume, or temperature of a gas, given its initial conditions and changes in two of the three properties (pressure, volume, and temperature). The combined gas law is expressed as: (P1 * V1) / T1 = (P2 * V2) / T2

This calculator converts between the equilibrium constants Kp (expressed in terms of partial pressures) and Kc (expressed in terms of concentrations).

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

Calculates the relationship between volume and temperature of a gas at constant pressure using Charles's Law: V1/T1 = V2/T2.

Calculates the Gibbs Free Energy (ΔG) of a reaction to determine its spontaneity. A negative ΔG indicates a spontaneous reaction, a positive ΔG indicates a non-spontaneous reaction, and a ΔG of zero indicates equilibrium.

Calculates the vapor pressure of a substance at a given temperature using the Clausius-Clapeyron equation. This calculator helps explore phase transitions and thermodynamics.
