Explanation The given chemical reaction is as follows. A(s) + B +2 (aq) → A +2 (aq) + B(s) ΔG=-14 .0kJ From the above reaction A is oxidized into A +2 and it is occurs at anode. B +2 is reduced into B and it is occurs at cathode. Let’s write the half cell reactions of the given chemical reaction. A(s) + B +2 (aq) → A +2 (aq) + B(s) At anode : A(s) → A +2 (aq)+2e - At cathode : B +2 (aq)+2e - → B(s) Formula used: ΔG o = -nFE cell 0 ΔG rxn = ΔG o + RT lnQ Q = [Products] [Reactants] Calculation: Let’s calculate the E 0 cell of the reaction. The E 0 cell of this reaction is calculated by the following formula. ΔG o = -nFE cell 0 ΔG o = - 14 .0 × 10 3 J n = 2 mol Substitute the values, - 14 .0 × 10 3 J = -2 mol× ( 96485 C mol ) ×E cell o E cell o = -14 .0×10 3 J -2 mol× ( 96485C mol ) = 0 .0726V a. A +2 = 1.00M and B +2 =1.00M First, let’s calculate the Q of the reaction Q = [products] [Reactants] = [A +2 ] [B +2 ] = 1 .00M 1 .00M =1 Let’s calculate the E cell of the reaction. E cell can be calculated by the following formula. E cell = E cell o - 0 .0592V n logQ E 0 cell = 0.0726V n = 2 Substituting the values in the above formula, = + 0 .0726V- ( 0 .0592V 2 log 1 ) = +0 .0726V Let’s calculate the ΔG rxn of the reaction. ΔG rxn can be calculate by the following formula. ΔG rxn = ΔG o + RT lnQ ΔG o = -14 .0 × 10 3 J R =8.314 J/mol K T = 298K Q = 1 Substituting the values in the formula, = -14 .0×10 3 J + ( 8 .314 J molK ×298K×ln(1) ) = -14 .0×10 3 J × ( 1kJ 1000J ) = -14 .0 kJ Therefore, Q , E cell , ΔG rxn of this reaction are 1, +0.0726V and -14.0 kJ respectively. b. B +2 =1.00M and A +2 = 1.00×10 -4 M First, let’s calculate the Q of the reaction Q = [products] [Reactants] = [A +2 ] [B +2 ] = 1 .00 × 10 − 4 M 1 .00M =1 .00 × 10 − 4 Let’s calculate the E cell of the reaction. E cell can be calculated by the following formula. E cell = E cell o - 0 .0592V n logQ E 0 cell n = 2 Substituting the values in the above formula. = + 0 .0726V- ( 0 .0592V 2 log (1 .00 × 10 − 4 ) ) = +0 .191 V Let’s calculate the ΔG rxn of the reaction...
