Question

Flask $A$ contains $H_2$ gas and $B$ contains $C{H}_4$ gas have equal mass and volume at 300 $K$ and 600 $K$ respectively. Which of the flask will have greater compressibility factor?

Assuming ideal behavior for both the gases.

• A. Flask $A$
• B. Flask $B$
• C. Both $A$ and $B$ are equal
• D. None

Answer 1

The correct option is C Both $A$ and $B$ are equal

Since both of the gases A and B are ideal gas.

As $PV=nRT$ for ideal gases.

So, they have compressibility factor,

$Z=\frac{PV}{RT}=1$

Both of the gas will have the same compressibility factor.

Hence, option $\left(C\right)$ is correct.
