Thermodynamics Calculator
Calculate Gibbs energy from user-supplied enthalpy, entropy, temperature, and optional constant heat capacity.
V2 · Transparent calculation method
V2 calculates Gibbs energy from user-supplied reference thermodynamic values. It does not estimate absolute properties from SMILES.
