  • Question
  • Assertion (A): From the slope of the line in Figure, we can find permanent dipole moment of the molecules.

    Reason (R): Total polarization of a polyatomic gas is given by P = N(ae + ai + ?2p / 3kT)E.
    Assertion (A): From the slope of the line in Figure, we can find permanent dipole moment of the mole


  • Options
  • A. Both A and R are true and R is correct explanation of A
  • B. Both A and R are true but R is not correct explanation of A
  • C. A is true but R is false
  • D. A is false but R is true

  • Correct Answer
  • Both A and R are true and R is correct explanation of A 

    Explanation
    The slope of the line in figure is Assertion (A): From the slope of the line in Figure, we can find permanent dipole moment of the mole.

    Since the total polarization is as given by the expression, we can find the permanent dipole moment of the molecules from the slope.
