1.	A gas at 350 K and 15 bar has molar volume 20 percent smaller than that for an ideal gas under the same conditions. The correct option above the gas and its compressibility factor (Z) is :A. Z lt 1 and repulsive forces are dominantB. Z gt 1 and attractive forces are dominant.C. Z gt 1 and repulsive forces are dominant.D. Z lt 1 and attractive forces are dominant
Answer» Correct Answer - D `V_(i)=V`, ltrgt `V_(r)=V-0.2V=0.8V` if value of Zlt1 then attractive forces are dominant, `(Z=(V_(r))/(V_(i))=0.8)`
