Question

what is virial coefficient in chemistry

Answer 1

Definition of virial coefficient. : one of the coefficients in a series of terms involving inverse powers of specific volume whose sum represents the product of specific volume by pressure for a pure gas.

Gas Laws The actual behavior is often described with the virial equation: PV = nRT[1 + B(n/V) + C(n/V)2 + ...] , in which the temperature-dependent constants for each gas are known as the virial coefficients. The second virial coefficient, B , has units of molar volume (L/mole).
