This question has multiple parts. Work all the parts to get the most points. The Gibbs Free Energy equation is given by the equation: AG = AH - TAS Where: AG = Gibbs Free Energy change AH = Enthalpy change T = temperature AS = Entropy change In order to solve for the temperature, T, in two steps you must: Step One Add the same expression to each side of the equation to leave the term that includes the variable by itself on the right-hand side of the expression: (Be sure that the answer field changes from light yellow to dark yellow before releasing your answer.) +AG = +AH - TAS Drag and drop your selection from the following list to complete the answer: 1 1 -ΔΗ ΔΗ AH AH

5. Consider a lattice gas of N particles distributed cells (with N < V). Suppose that each cell may be either empty or occupied by a single particle. The number of microscopic states of this system will be given by among V! N (V, N) = N! (V – N)! Obtain an expression for the entropy per particle, s = s where v = V/N. From this fundamental equation, obtain an expression for the equation of state p/T. Write an expansion of p/T in terms of the density p = 1/v. Show that the first term of this expansion gives the Boyle law of the ideal gases. Sketch a graph of u/T, where u is the chemical potential, in terms of the density p. What is the behavior of the chemical potential in the limits p → 0 and p → 1?

Combustion of glucose (CH,0 is the main source of energy for animal cells: CH,0,) + 60,(g) -- 6CO,(g) + 6H,o) AG,(37 C) =- 2872. kI One of the most important uses to which this energy is put is the assembly of proteins out of amino acid building blocks. The Gibbs free energy of formation of one peptide bond, joining one amino acid to another, is 21 k/mol. Suppose some cells are assembling a certain protein made of 84 amino acids. (Note that the number of peptide bonds in the protein will be one less than the number of amino acids.) Calculate the minimum mass of glucose that must be burned to assemble 400. umol of this protein. Round your answer to 2 significant digits.
