can you please explain how to get these answers. (showing your work)

Assume heteronuclear diatomic molecules, AB, forms a one-dimensional crystal by lining up along the x- axis. Also assume that each molecule can only have one of six possible orientations, corresponding to atom A facing in either the positive or negative direction along the x-, y-, or z-axis. If the molecules are arranged randomly in the six directions, calculate the entropy of one mole of AB molecules at absolute zero. 14.9 J/K 89.6 J/K 4.53 times 10^-21 J/K 0 J/K In biological systems, complex molecules can be made using free energy from the conversion of ATP^4- to ADP^3-. How many moles of ATP^4- are needed to provide the free energy for to turn 1 mol of A into B and what is delta G degree for the overall reaction? 1 mole of ATP^4- and delta G degree = 69.5 kJ 10 moles of ATP^4- and delta G degree = -100 kJ 3 moles of ATP^4- and delta G degree = 8.5 kJ 4 moles of ATP^4- and delta G degree = -22 kJ 10 moles of ATP^4- and delta G degree degree = -205 kJ

Explanation / Answer

10) Given that n = 1 mol

                     no of orienations = no of microstates = 6

Hence,

Entropy at absolute zero

             S = nR In(N) N = no of orientations

                = 1 mol x 8.314 J/K/mol x In(6)

               = 14.9 J/K
