Chemical Thermodynamics calculators
11 calculators Boiling Point Elevation Calculator Calculate boiling point elevation with ΔTb = i·Kb·m. Pick a solvent preset, choose a solute, enter mass or molality, and reverse-solve for any variable.
Open Entropy Calculator Calculate entropy change four ways: heat/temperature (Q/T), reaction (products minus reactants), isothermal ideal gas, or Gibbs free energy. Full worked steps included.
Open Freezing Point Depression Calculator Calculate freezing point depression (ΔTf = i·Kf·m), find the new freezing point, reverse-solve for molality or molar mass. Supports 8 solvents and Fahrenheit.
Open Gibbs Free Energy Calculator Calculate Gibbs free energy (ΔG) from ΔH, T, ΔS; solve for any variable; find ΔG° from K or ΔG from Q. Celsius, Fahrenheit, and calorie unit support.
Open Boiling Point at Altitude Calculator Find the boiling point of water at any altitude or pressure. Uses the Antoine equation and barometric formula. Metric and imperial, instant results.
Open Boiling Point Calculator Calculate the boiling point of water at any altitude or pressure, or find the boiling point elevation of a solution. Metric and imperial, instant results.
Open Gibbs' Phase Rule Calculator Calculate thermodynamic degrees of freedom with the Gibbs phase rule. Supports reactive systems, fixed T or P constraints, and all common phase equilibria.
Open Heat of Combustion Calculator Calculate heat of combustion from calorimetry data or standard formation enthalpies. Get results in kJ/mol, kJ/g and MJ/kg with a step-by-step worked solution.
