Calculate the change in entropy that occurs when 18.02 g of ice at 210.0oC is placed in 54.05 g of water at 100.0oC in a perfectly insulated vessel. Assume that the molar heat capacities for H2O(s) and H2O(l) are 37.5 JK-1mol-1 and 75.3 JK-1mol-1, respectively, and the molar enthalpy of fusion for ice is 6.01 kJ/ mol.
Answer to relevant QuestionsThe synthesis of glucose directly from CO2 and H2O and the synthesis of proteins directly from amino acids are both non-spontaneous processes under standard conditions. Yet these processes must occur for life to exist. In ...For each of the following pairs of substances, which sub-stance has the greater value of S8 at 25oC and 1 atm? a. Cgraphite(s) or Cdiamond(s) b. C2H5OH(l) or C2H5OH(g) c. CO2(s) or CO2(g) d. N2O(g) or He(g) e. HF(g) or ...For mercury at 1 atm, the enthalpy of vaporization is 58.51 kJ/mol and the entropy of vaporization is 92.92 J K-1mol-1. What is the boiling point of mercury? For the reaction at 298 K, 2NO2(g) ⇌ N2O4(g) the values of ΔHo and ΔSo are –58.03 kJ and –176.6 J/ K, respectively. What is the value of ΔGo at 298 K? Assuming that ΔHo and ΔSo do not depend on temperature, at ...ΔG predicts spontaneity for a reaction at constant T and P, whereas ΔGo predicts the equilibrium position. Explain what this statement means. Under what conditions can you use ΔGo to determine the spontaneity of a ...
