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 calculatorBond enthalpy
Estimate reaction enthalpy from average bond enthalpies by summing bonds broken minus bonds formed.
Open calculatorHess / formation enthalpy
Calculate reaction enthalpy from standard enthalpies of formation using products minus reactants.
Open calculatorGibbs energy (HL)
Calculate standard Gibbs energy from enthalpy, entropy and temperature, or obtain an equilibrium constant from ΔG°.
Open calculatorE°cell & ΔG° (HL)
Calculate standard cell potential from cathode and anode reduction potentials, then convert E°cell to ΔG°.
