Question

Determine how many of the following statements are true at very high pressure for a real gas:
$\left(a\right)$ Compressibility factor is greater than $\text{1}\text{.}$
$\left(b\right)$ Compressibility factor varies linearly with pressure.
$\left(c\right)$ Molar volume occupied by gas is more as compared to ideal gas at similar pressure and temperature.
$\left(d\right)$ Gas is less compressible as compare to ideal gas.
$\left(e\right)$ Compressibility factor is given by $Z=1+\frac{Pb}{RT}.$

Answer 1

Answer: 5

At high pressure $Z>1$ i.e. repulsive forces are relatively dominant, so gas is less compressible.
At high pressure, $a\cong 0$.
