2. Polyatomic gas molecules can store energy in many degrees of freedom (DOF). To formulate a partition function ( z ) that adequately describes the molecule, all DOF's must be accounted for: a. How many of what types of DOFs does ammonia (NH3) have? b. Write an expression for ztrans using its individual translational DOFs. c. Using the same approach as in part b, express ztotal in terms of the partition functions of all DOF's
