The square-well potential function is given by:
Answer the following questions:
(a) Sketch a plot of square-well potential energy versus distance.
(b) Using this potential function, develop an expression for the second virial coeffi cient.
(c) For CH4, the parameters are reported to be σ1 = 2.856, σ2 = 4.678, and ε/k is 132.2. Calculate the value of B for methane at 200 K and 400 K. Compare the results to the experimental values reported in Example 4.9.
Example 4.9
