How can standard enthalpy and gibbs free energy of a reaction be used to determine yield at a particular temperature and pressure? The standard enthalpy of formation at 298K is -45.4 kJ/mol and the standard gibbs free energy at 298K is -7.7kJ/mol. The problem requires that the yield of the reaction be determined at 325K and 50 atm. Any help with this would be greatly appreciated.

Cyanide ion, CN-, is important in metal plating industries as well as in leaching matals from ores because it keeps metals dissolved under conditions where they would otherwise form solids (precipitate) and settle out of solution. It is important to maintain pH>10.5 in these solutions to avoid forming toxic hydrogen cyanide gas. If a solution is prepared by dissolving 10-2M NaCN in water, will the pH be in the region where the solution is safe? What is {HCN} in the solution? The pKa of HCN is 9.24.

Balancing Redox Equations in Acidic or Basic Solutions

In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods. The oxidation number method balances the net increase in oxidation of the substance oxidized with the net decrease in the oxidation number of the substance reduced. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In both methods

H2O(l),OH?(aq), and H+ (aq) may be added to complete the mass balance. Which substances are used depends on the reaction conditions.

Acidic solution

In acidic solution, bromate ion can be used to react with a number of metal ions. One such reaction is

BrO3?(aq)+Sn2+(aq)?Br?(aq)+Sn4+(aq)

Since this reaction takes place in acidic solution,

H2O(l)andH+(aq) will be involved in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:

BrO3?(aq)+Sn2+(aq)+ ____ ?Br?(aq)+Sn4+(aq)+ ___

Part A

What are the coefficients of the six species in the balanced equation above? Remember to include coefficients for

H2O(l)andH+(aq)

in the appropriate blanks.

Enter the equation coefficients in order separated by commas (e.g., 2,2,1,4,4,3).

     

Basic solution

Potassium permanganate,

KMnO4, is a powerful oxidizing agent. The products of a given redox reaction with the permanganate ion depend on the reaction conditions used. In basic solution, the following equation represents the reaction of this ion with a solution containing sodium sulfite:

MnO4?(aq)+SO32?(aq)?MnO2(s)+SO42?(aq)Since this reaction takes place in basic solution,H2O(l)andOH?(aq)

will be shown in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:

MnO4?(aq)+SO32?(aq)+ ____?MnO2(s)+SO42?(aq)+ ___

Part B

What are the coefficients of the six species in the balanced equation above? Remember to include coefficients for

H2O(l)andOH? (aq) in the blanks where appropriate.

Enter the equation coefficients in order separated by commas (e.g., 2,2,1,4,4,3).

Suppose you titrated your standard acid (KHP) with the base to be standardized, but added several drops extra of the base (i.e. stopped the titration after the phenolphthalein indicator in the solution turned very pink).

If this calculated value was used to determine the molar mass of the unknown acid, what type of error would you have for the molar mass of the unknown acid? (i.e. would you overestimate or underestimate the molar mass value?) Support your answer by, for every step in the calculation, determining whether the calculated value would be greater or less than it should be.
