Question

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

• A. $V _ { m } > 22.4$litres
• B. $V _ { m } < 22.4$litres
• C. $V _ { m } = 22.4$litres
• D. $V _ { m } = 44.8$litres

Answer 1

Answer: (B)

$V _ { m } < 22.4$litres

Answer 2

Compressibility = $\frac { P V } { n R T } < 1$ at STP (as given)

$n R T > P V$ R = 0.821

$N \times 0.0821 \times 273 > 1 V _ { m }$ T = 273^oK

P­ = 1

n = 1
