Unformatted text preview: that
is given by and that the result given in Problem 21-6 follows.
A. In Problem 21-4, ethane is heated at constant volume, so (assuming ideal behavior) Likewise, in Problem 21-5, the system is kept at constant pressure and so These values correspond to those shown in the diagram. Now, path C represents an isothermal
process. Because we are assuming ideal behavior,
, which means that
. Then we can write as (Equation 20.22) Note that path A is equivalent to the sums of paths B and C, so
, we can write . Because an...
