Question

The compressibility factor of gas is less than unity at STP, therefore:
(V${}_m$ is the molar volume)

• 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

The correct option is B V${}_m$ < 22.4 L

Compression factor, $Z$ $=\frac{V_{real}}{V_{ideal}}$
Now, $Z$ $<$ 1 $⟹V_{real}<V_{ideal}$
So, the gas will have a volume less than 22.4 L.
