Question

For the non-zero value of the force of attraction between gas molecules, gas equation will be:

• A. $PV=nRT-\frac{n^{2}a}{V}$
• B. $PV=nRT+nbP$
• C. $PV=nRT$
• D. $P=\frac{nRT}{V-b}$

Answer 1

The correct option is A $PV=nRT-\frac{n^{2}a}{V}$

when $\frac{n^{2}a}{V^2}\ne 0$

$[P+\frac{n^{2}a}{V^2}]V=nRT$

$PV+\frac{n^{2}a}{V}=nRT$

$PV=nRT-\frac{n^{2}a}{V}$

Hence, the correct option is $\text{A}$
