Energetics & electrochemistry Calculators

Work through calorimetry, enthalpy cycles, bond enthalpies, Gibbs energy and electrochemical relationships.

Calorimetry

Calculate heat transferred and molar enthalpy from mass, specific heat capacity, temperature change and amount reacted.

Open calculator

Bond enthalpy

Estimate reaction enthalpy from average bond enthalpies by summing bonds broken minus bonds formed.

Open calculator

Hess / formation enthalpy

Calculate reaction enthalpy from standard enthalpies of formation using products minus reactants.

Open calculator

Gibbs energy (HL)

Calculate standard Gibbs energy from enthalpy, entropy and temperature, or obtain an equilibrium constant from ΔG°.

Open calculator

E°cell & ΔG° (HL)

Calculate standard cell potential from cathode and anode reduction potentials, then convert E°cell to ΔG°.
