Calculate a value for the equilibrium constant for the reaction (6)*O = (6)0 + (6) ²0 given hv NO2 (9) NO(g) + O(g) K = 2.3 x 10-49 O3 (9) + NO(9) = NO,(g) + O2(9) K = 8.4 x 10-34 (Hint: When reactions are added together, the equilibrium expressions are multiplied.) K =
A 0.010 M solution of the weak acid HA has an osmotic pressure (see chapter on solutions and colloids) of 0.293 atm at 25 C. A 0.010 M solution of the weak acid HB has an osmotic pressure of 0.345 atm under the same conditions. (a) Which acid has the larger equilibrium constant for ionization HA[HA(aq)A(aq)+H+(aq)] or HB[HB(aq)H+(aq)+B(aq)]? (b) What are the equilibrium constants for the ionization of these acids? (Hint: Remember that each solution contains three dissolved species: the weak acid (HA or HB). the conjugate base (A- or B- and the hydrogen ion (H+). Remember that osmotic pressure (like all colligative properties) is related to the total number of solute particles. Specifically for osmotic pressure, those concentrations are described by molarities.)

Consider the following equation: 2SO2(g)+O2(g)=2SO3(g). At 700 0C, a 500mL reaction vessel contains 1.20*10-3 mol of SO2, 5.0*10-4 mol of O2 and 1.0*10-4 mol of SO3. (a) If Kc is 1.7*106 at 700 0C, will the reaction favor the formation of more products or reactants? (b) what are the equlibrium concentrations of the products and reactants?
The brackets ([ ]) used in an equilibrium constant expression represent O the physical state of the species O the concentration of the species at STP O the concentration of the species in terms of molarity O the concentration of the species at equilibrium
The preparation of an aqueous solution is described in the table below. For this solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, ar formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that NH, is a weak base. . acids: 2.2 mol of HCl is added to bases: 1.0 L of a 1.4 M NH, solution. other:

Three students are comparing the solubility of Ce2(SO4 )3 , K2Cr2O7 and KClO3 at 50oC. Student 1 thinks that KClO3 has the greatest solubility. However, student 2 thinks that K2Cr2O7 has the greatest and student 3 thinks it is Ce2(SO4 )3. Which student do you agree with and why?
