Question

A gas at 350 K and 15 bar has molar volume
rcent smaller than that for an ideal gas under
the same conditions. The correctloption about
the gas and its compressibility factor (Z) is :
Z>land repulsive forces are dominant
(2) Z<land attractive forces are dominant
| Z<1 and repulsive forces are dominant
(4) Z>1 and attractive forces are dominant
help me please​

Answer 1

Answer:

compressibility factor(Z)=$\frac{V_{real} }{V_{ideal} }$

$V_{real}$<$V_{ideal}$

Hence Z<1

If Z < 1, attractive forces are dominant among gaseous molecules and liquefaction of gas will be easy.

Answer 2

Answer:

Explanation:

Vi = V

Vr = V - 0.2 V = 0.8 V

if value of Zlt 1 then attractive forces are dominant,

( Z = Vr/Vi) = 0.8
