JEE Main 2023 (Online) 29th January Morning Shift Chemistry - Gaseous State Question 7 English

What is the value of compressibility factor at point A ?

Multiple Choice Options

  • A 1+bV
  • B 1−aRTV
  • C 1+aRTV
  • D 1−bV

Step-by-Step Verified Solution

For 1 mole of real gas

PV=ZRT\mathrm{PV}=\mathrm{ZRT}

from graph PV for real gas is less than PV for ideal gas at point A\mathrm{A}

\mathrm{Z} < 1

Z=1−aVmRT\mathrm{Z}=1-\frac{\mathrm{a}}{\mathrm{V}_{\mathrm{m}} \mathrm{RT}}
