Scientific Basis of the Chemical Potential Calculator
Chemical potential (μ) is defined as the partial derivative of Gibbs free energy (G) with respect to the number of moles (n) of a substance at constant temperature (T) and pressure (P):
\[ \mu_i = \left( \frac{\partial G}{\partial n_i} \right)_{T,P,n_j} \]
For an ideal gas, the chemical potential is calculated using:
\[ \mu = \mu^0 + RT \ln\left(\frac{P}{P^0}\right) \]
Where:
- \( \mu^0 \): Standard chemical potential at standard pressure (\( P^0 = 1 \, \text{atm} \)).
- \( R \): Universal gas constant (8.314 J/(mol·K)).
- \( T \): Temperature in Kelvin.
- \( P \): Pressure in atmospheres.
For liquids or solutions, the chemical potential includes a mole fraction term:
\[ \mu = \mu^0 + RT \ln(x) \]
Where \( x \) is the mole fraction of the substance in the solution. The calculator uses standard chemical potential values (\( \mu^0 \)) sourced from thermodynamic databases for water and ethanol, and assumes ideal gas behavior for gases. These equations are derived from rigorous thermodynamic principles and are widely accepted in scientific literature.
