Question

The compressibility of a gas is less than unity at STP. Therefore,

• A. $V_m > 22.4 L$
• B. $V_m < 22.4 L$
• C. $V_m - 22.4 L$
• D. $V_m = 44.8 L$

Answer 1

Answer: (B)

$V_m < 22.4 L$

Answer 2

Compressibility factor (Z) $=\frac{V}{V_{id}} < 1$(given)
$\Rightarrow \, \, \, \, \, \, \, \, \, \, \, \, \, \, V < 22.4 L$
$\because \, \, \, \, \, \, \, \, \, \, \, V_{id}$(1 mol )=22.4 L at STP
