Compressibility Factor

Formula

Z = PV_m / (RT)

Where:

  • Z = compressibility factor (dimensionless)
  • P = pressure (atm)
  • V_m = molar volume (L/mol)
  • R = 0.08206 L·atm/(mol·K)
  • T = temperature (K)

    • For an ideal gas, Z = 1. Z < 1 means attractive forces dominate; Z > 1 means repulsive forces dominate.

    Ejemplo Resuelto

    A gas at 100 atm, 300 K, has a molar volume of 0.2 L/mol.

    1. Z = PV_m / (RT)
    2. Z = (100 × 0.2) / (0.08206 × 300)
    3. Z = 20 / 24.618
    4. Z = 0.8124
