  • I need help with For the non-zero values of force of attraction between gas molecules, gas equation will be :

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

  • Option 1)

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

  • Option 2)

    PV = nRT + nbP

  • Option 3)

    PV = nRT

  • Option 4)

    P = \frac{nRT}{V - b}

 

Answers (1)

As we learnt in

Vander waal equation for real gas -

\left (p+\frac{an^{2}}{v} \right )(V-nb)=nRT

- wherein

a, b : Vander waal Constants, P- Pressure, V- Volume, n- No. of moles, R- Gas Constant, T- Temperature

 

\\ \left ( P \right )\left ( V-nb \right )= nRT \\*\\ P= \frac{nRT}{V-nb}


Option 1)

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

Correct

Option 2)

PV = nRT + nbP

Incorrect

Option 3)

PV = nRT

Incorrect

Option 4)

P = \frac{nRT}{V - b}

Incorrect
