Morse Equation
The Morse equation relates osmotic pressure to solute concentration. Osmotic pressure is the minimum pressure that needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.
The osmotic pressure equals the product of the molar gas constant, van 't Hoff factor, molarity and temperature.
