Question

Pressure deviation from ideal behaviour takes place because of

• A. molecular interaction between atoms and $\frac {PV} {nRT} > 1$
• B. molecular interaction between atoms and $\frac {PV} {nRT} < 1$
• C. finite size of atoms and $\frac {PV} {nRT} > 1$
• D. finite size of atoms and $\frac {PV} {nRT} < 1$

Answer 1

Answer: (A)

molecular interaction between atoms and $\frac {PV} {nRT} > 1$

Answer 2

$\frac{p V}{n R T} > 1$, the gas is less compressible the expected from ideal behaviour and shows positive deviation.
