Chemical Potential Calculator

Calculate the chemical potential (partial molar Gibbs energy) for various systems.

System Type

Temperature (K)

Standard Chemical Potential μ° (kJ/mol)

Pressure (Pa)

Standard Pressure P° (Pa)

Chemical Potential μ: -200.000000 eV

Standard Potential μ°: -200.0000 kJ/mol

Correction Term: 0.0000 kJ/mol

Ideal gas: μ = μ° + RT ln(P/P°)

Solution: μ = μ° + RT ln(a)

Electron gas: EF = (ℏ²/2m)(3π²n)^(2/3)

Finite T: μ ≈ EF[1 - (π²/12)(kT/EF)²]

Chemical potential = partial molar Gibbs energy = (∂G/∂n)_T,P
