Constants needed: R-8.314 J mol/K, F-96,485 C/mol 1. The rusting of iron is spontaneous and is accompanied by a decrease in the entropy of the entropy change of the system (the iron and oxygen). Why? What can we conclude about the surroundings? (7 pts)
Constant: R -8.314 J K mol-0.08314 dmbar K'mol-0.08206 dm atm K mol (3 Points) A container is divided into two equal compartments. Suppose that 2.0 mol H2 at 2.0 atm and 25 °C and 4.0 mol N2 at 3.0 atm and 25 °C are mixed by removing the partition between them. Calculate AmixG.
AG°= AH-TAS AG=AGº+RTinQ where R=8.314 J/mol K 1. Calculate AGº for the following reaction at 25 °C if AH°= -1854 kJ/mol; AS°= -236 J/mol K CH-COCH3(g) + 402(g) → 3C02(g) + 3H2O(1) 2. NH.NO, dissolving in water is a spontaneous process. As it dissolves, the temperature of the solution decreases. Based on this, what must the signs (positive or negative) of AG, AH, and AS be?
