Chemical Potential Calculator
Calculate chemical potential using activity, pressure, and temperature. mu = mu0 + RT*ln(a)
mu = mu0 + RT*ln(a)
System Type:
Chemical Potential (mu)
-237.1000 kJ/mol
Chemical Potential Formula:
mu = mu0 + RT * ln(a)
mu = chemical potential (J/mol)
mu0 = standard chemical potential
R = 8.314 J/(mol*K)
T = temperature (K)
a = activity (dimensionless)
Calculation:
mu = -237.1 + (8.314 * 298.15 * ln(1)) / 1000
mu = -237.1000 kJ/mol
Understanding Chemical Potential
Chemical potential (mu) is the partial molar Gibbs free energy of a component in a mixture. It represents the change in Gibbs energy when one mole of a substance is added to a system at constant temperature, pressure, and composition of other components. Chemical potential drives diffusion and chemical reactions - substances spontaneously move from regions of high chemical potential to regions of low chemical potential.
Applications
Phase Equilibria
At equilibrium, chemical potential is equal in all phases
Osmotic Pressure
Drives water movement across semipermeable membranes
Electrochemistry
Related to electrode potential and cell EMF
Chemical Reactions
Determines reaction spontaneity and equilibrium
