State Hund's rules for identifying lowest energy states in atomic spectroscopy. The term symbols for a $nd^2$ electron configuration are $^1S$, $^1D$, $^1G$, $^3P$ and $^3F$. (i) Use the first two rules stated in part (a.) above to order these terms according to energy. (ii) Calculate the values of J associated with each of these term symbols. (iii) Use the third rule to complete the energy ordering from lowest to highest indicating which term represents the ground state. (iv) What would the ground state be of a $nd^8$ electron configuration? Justify your answer.

A continuous fractionator is to be designed for separating a feed mixture containing equimolar amounts of CCl and CS2, to get a top product containing 95% CS2 and bottom product containing 6% CS2, at 1 atm pressure. The feed is saturated vapor and fed at the rate of 5000 kg/h. A total condenser is used and reflux is returned to the top plate as a saturated liquid. The equilibrium data is given below: x 0 0.06 0.11 0.26 0.39 0.53 0.66 0.76 0.86 1 y 0 0.16 0.27 0.50 0.63 0.75 0.83 0.88 0.93 1 (i) Determine the flow rate of top and bottom product (ii) Calculate the theoretical number of trays required if a reflux ratio of 2 times minimum Rm is used (iii) Locate the feed tray
