Question

In lecture I mentioned that standard state is usually at 25^oC; however, it can be at any specified temperature. In problems 9 and 10 you will calculate ΔG^o from K_sp data. The K_sp range over the temperature range in these two problems is consistent with some actually solubility data; however, in order to allow each student to do their own calculation I have made this data for an "unknown" ionic solid.

Calculate the value of ΔG^o at 5.9^oC for the dissolution of an ionic solid with a K_sp of

2.5 x 10^-11 at 5.9^oC.

Your answer should have 2 sig figs.

At 298K, NH4NO3 readily dissolves in water, suggesting that the change in free energy (ΔG) favors the dissolution process. However, when NH4NO3 dissolves in water, the temperature of the water decreases. The particulate diagram above attempts to provide a microscopic view of the dissolution of NH4NO3(s) considering both the change in enthalpy (ΔH) and the change in entropy (ΔS). Which of the following explains what the particle diagram is able to illustrate and why? (see attached image) a.) The particle diagram is able to illustrate that the ΔH for the dissolution of NH4NO3 is exothermic because overcoming the attractive forces between the ions requires the absorption of energy. b.) The particle diagram is able to illustrate that the ΔH for the dissolution of NH4NO3 is endothermic because forming new interactions between the ions and the water molecules releases energy. c.) The particle diagram is able to illustrate that entropy increases when NH4NO3(s) dissolves in water…
Calculation of the entropy of mixing for each mixture: You measured the exact temperature at which the test tubes passed from one to two phases. If the enthalpy of mixing for the two test tubes are 1.24 kJ/mol and –1.71 kJ/mol (which number refers to which test tube?), what is the entropy of mixing for each system? Show your work. ΔG (0) = ΔH - TΔS (Gibbs energy is 0) Justification for your calculation: [do not simply tell me what you did. Explain the chemical principles that were involved in deciding to manipulate the numbers the way you did.] Temperature for methanol/cyclohexane mixture is 51 degree celsius and Temperature for water/triethylamine mixture is 6 degree celsius

The standard molar entropy of rhombic sulfur is 31.80 J K−1 mol−1, and that of monoclinic sulfur is 32.6 J K−1 mol−1. At what temperature will the transition occur at 1 bar? _______ K. 3 sig. fig.
A student poured 100 ml of water (density = 1.00 g / mL) into a coffee calorimeter, noted that the temperature of the water was 18.8oC, then added 5.33 g KOH. With the lid on, the mixture was stirred, temperature increased and the maximum temperature reached at the time of mixing 31.6 oC. Calculate the heat of the system in this dissolution reaction (qsys). ( Approximate the specific heat capacity, cp as 4.18 J g-1 K-1. Do not consider the contribution to the heat generated from the calorimeter; assume that this is zero. Only calculate the heat from the heat capacity of the solution. make sure you consider the sign of qsys qsys for dissolution of KOH = J
The solubility of magnesium oxalate, MgC2O4, in water is (7.70x10^0)x10-3 mol/L. What is the Ksp for this salt? Express your answer to three significant figures. Note: Your answer is assumed to be reduced to the highest power possible.
In an experiment the solubility of KNO3 in water was measured of the readily soluble substance at different temperatures and determined four important termodynamic quantities (ΔH0, ΔG0, ΔS0, and K298) for the dissolution process. The same four thermodynamic quantities can be be determined for the dissolution of a sparingly soluble substance in water such as benzoic acid, but the numerical values are then quite different and reflect the differentiation between readily and sparingly soluble substances in water. Predict how you expect each of the four thermodynamic quantities for the dissolution of benzoic acid in water will differ from the values determined for the dissolution process of potassium nitrate.
