The validation corresponding to the precipitation of lead (II) chloride taking place when 185 mL of 0.025 M NaCl is added to 235 mL of 0.165 M Pb ( ClO 4 ) 2 is to be stated. Concept introduction: The solubility product is the mathematical product of a substance’s dissolved ion concentration raised to its power of its stoichiometric coefficients. When sparingly soluble ionic compound releases ions in the solution, it gives relevant solubility product. The solvent is generally water. To determine: The validation corresponding to the precipitation of lead (II) chloride taking place when 185 mL of 0.025 M NaCl is added to 235 mL of 0.165 M Pb ( ClO 4 ) 2 .

Question

The table includes macrostates characterized by 4 energy levels (&) that are equally spaced but with different degrees of occupation. a) Calculate the energy of all the macrostates (in joules). See if they all have the same energy and number of particles. b) Calculate the macrostate that is most likely to exist. For this macrostate, show that the population of the levels is consistent with the Boltzmann distribution. macrostate 1 macrostate 2 macrostate 3 ε/k (K) Populations Populations Populations 300 5 3 4 200 7 9 8 100 15 17 16 0 33 31 32 DATO: k = 1,38×10-23 J K-1
