Question: 8 . ( 2 0 min. Variational method for ensembles. ) A . Consider the grandcanonical ensemble. Use entropy maximum principle applied to the expression

8.(20 min. Variational method for ensembles.) A. Consider the grandcanonical ensemble. Use entropy maximum principle applied to the expression of the entropy log with the constraints P and obtain the grandcanonical partition function. Explain how you can get and from the partition function. B. Consider canonical ensemble. Use the entropy maximum principle applied to the expression of the entropy log with the constraints P and obtain the canonical partition function. Explain how you can get from the partition function.
