Interpretation: The distribution of molecular velocities at
Concept introduction: The fraction of molecules that have the speeds over the range
Answer to Problem 1B.1P
The values of
The values of
The values of calculated intensity correspond to the given values of intensity.
Explanation of Solution
The expression for the distribution of molecular velocity in the x-direction is,
Where,
The expression for the time required to displace the slots by
Where,
The expression to calculate the velocity in the x-direction with disk separation of
Substitute the values of time and disk separation in the above equation.
The relative intensity is directly proportional to velocity distribution of the molecules. Substitute the value of
Substitute the exponential term in equation (1) so as to obtain the formula for relative intensity.
Substitute the values of
Hence, the value of
Substitute the value of
Hence, the value of
Similarly, the values of
The values of
Thus, the values of calculated intensity correspond to the given values of intensity.
