Question
![5. Consider the process where nA mol of gas A initially at 1 bar
pressure mix with ng mol of gas B also at 1 bar to form 1
mol of a uniform mixture of A and B at a final total pressure
of 1 bar, and all at constant temperature T. Assume that all
gases behave ideally.
a. Show that the entropy change, AmixSm, for this process
is given by AmixSm= -XARln XA - XBRln XB, where XA
ХА
and xg are the mole fractions of A and B, respectively.
b. If the motor will not work as described, what simple change
will allow it to work? Clearly, if the motor will work as
described, you need not answer part (b). This problem is
discussed in The Feynman Lectures on Physics, Vol. 1.
