The strongest known chemical bond is that in carbon mon- oxide, CO, with bond enthalpy of 1.05 × 10³ kJ mol-!. Furthermore, the entropy increase in a gaseous dissociation of the kind AB =A+B is about 110 J mol¬1 K-1. These factors establish a temperature above which there is essen- tially no chemistry of molecules. Show why this is so, and find the temperature.

An organic compound CXH,O is a liquid at room temperature. The normal freezing point of this compound is -30 °C, and its molar enthalpy of fusion is AH = 4.73 kJ/mol. What is the entropy change in unit of J/K when 0.29 mole of liquid CyHyO freezes at the normal freezing point? fus Please keep your answer to one decimal place.
Ice is heated at a constant pressure until it melts and vaporizes. What signs are associated with the total change in entropy and enthalpy (AS and AH) for this sample of water? AS=+, AH =+ ΔS = –, ΔΗ = - AS =-, AH = + AS = +, AH = -
Do not give handwriting solution. Calculate the entropy change, ΔS, for the following processes. If needed, Cp(O2)= 29.4 J mol-1 K-1 and Cp(CO2) = 37.1 J mol-1 K-1.(a) The pressure of one mole of O2(g) is increased from P to 2P at 298 K.(b) The temperature of one mole of CO2(g) is increased from 298 K to 355 K at aconstant volume of 20.0 L.

A chemical engineer is studying the two reactions shown in the table below. In each case, he fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 133.0 °C and constant total pressure. Then, he measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of his measurements are shown in the table. Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then, decide whether, under the conditions the engineer has set up, the reaction is spontaneous, the reverse reaction is spontaneous, or neither forward nor reverse reaction is spontaneous because the system is at equilibrium. 2CH₂OH(g) + 30₂(g) → 2CO₂(g) + 4H₂O(g) 4H₂PO4(s) P4O10 (s) + 6H₂0 (1) AH-1353. kJ AS = -3331.

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.
