Why we use virial equation of state?

Since the perfect gas law is an imperfect description of a real gas, we can combine the perfect gas law and the compressibility factors of real gases to develop an equation to describe the isotherms of a real gas. This Equation is known as the Virial Equation of state, which expresses the deviation from ideality in terms of a power series in the density. The actual behavior of fluids is often described with the virial equation: PV = RT[1 + (B/V) + (C/(V^2)) + ...] , where, B is the second virial coefficient, C is called the third virial coefficient, etc. in which the temperature-dependent constants for each gas are known as the virial coefficients. The second virial coefficient, B, has units of volume (L).

Why we modify the second virial coefficient to reduced second virial coefficient?

Since the tabular nature of the generalized compressibility-factor correlation is a disadvantage, but the complexity of the functions Z(0) and Z(1) precludes their accurate representation by simple equations. Nonetheless, we can give approximate analytical expression to these functions for a limited range of pressures. So we modify the second virial coefficient to reduced the second virial coefficient.
