Unformatted text preview: U , S , G , and C v . 3. For the same lattice in number 2., but now with only 2 non-interacting particles, each of which can exist in only two states, such that E 1 = 3 kcal/mol and E 2 = 5 kcal/mol, calculate U , S , G , and C v . (Note that this is a simple model of a two-state equilibrium, such as a protein which can exist in either a folded or unfolded state, in solution.) 4. For 0.5 mol of O 2 at 0.1 atm., and 1000 K, compute U , S , G , and C v . You may treat O 2 as an ideal gas at these T and P conditions. Note that both O 2 and the O atom have a net spin of 1 in their ground states. Also the first excited electronic state of O 2 occurs at a thermal energy of 11,300 K and has a net spin of 1/2. The bond dissociation energy of O 2 , D o , is 117.1 kcal/mol and the thermal vibrational and rotational energies are 2230 K and 2.07 K respectively. Created on December 21, 2004...
