Question

If the compression factor of a gas is more than unity at $STP$, then the value of $V_m$ is:

• A. greater than $22.4d{m}^3$
• B. lesser than $22.4d{m}^3$
• C. equal to $22.4d{m}^3$
• D. dependent on its molecular mass

Answer 1

The correct option is A greater than $22.4d{m}^3$

Compression factor, $Z=\frac{V_{real}}{V_{ideal}}$
As $Z>1,⟹$ $V_{real}>V_{ideal}$
So, the gas will have a volume more that $22.4d{m}^3$.
