Dear friends...

Could you shed some light on this?

If we have K = y/x, would it be correct to say that it could be applied to calculations involving either ideal gas or real gas?

Can we have

K_i = y_i/x_i = ( fugacity.coeff_i^vap) / (fugacity.coeff_i^liq)

are they always interchangeable?

Thank you.

Marcio
