(a)
Interpretation:
The slopes of three functions should be explained.
Concept introduction:
Ellingham diagram is a plot of ΔG versus temperature. Unless a phase change occurs, the Ellingham plot can be drawn as straight line, as ΔH and ΔS are constant with temperature unless a phase change occurs. In an Ellingham plot ΔS is the slope and ΔH is the y − intercept.
(b)
Interpretation:
The relation of ΔrG0 for the reaction

- Three reactions very important to the semiconductor industry are The reduction of silicon dioxide to crude silicon, SiO2(s) + 2 C(s) → Si(s) + 2 CO(g) ΔrH° = 689.9 kJ/mol The formation of silicon tetrachloride from crude silicon, Si(s) + 2 Cl2(g) → SiCl4(g) ΔrH° = −657.01 kJ/mol The reduction of silicon tetrachloride to pure silicon with magnesium, SiCl4(g) + 2 Mg(s) → 2 MgCl2(s) + Si(s) ΔrH° = −625.6 kJ/mol Calculate the overall enthalpy change when 1.00 mol sand, SiO2, changes into very pure silicon by this series of reactions.arrow_forwardA constant current of 1.40 amp is passed through an electrolytic cell containing a 0.100 M solution of AgNO3 and a silver anode and a platinum cathode until 2.48 g of silver is deposited. a How long does the current flow to obtain this deposit? b What mass of chromium would be deposited in a similar cell containing 0.100 M Cr3+ if the same amount of current were used?arrow_forwardA constant current of 1.25 amp is passed through an electrolytic cell containing a 0.050 M solution of CuSO4 and a copper anode and a platinum cathode until 3.00 g of copper is deposited. a How long does the current flow to obtain this deposit? b What mass of silver would be deposited in a similar cell containing 0.15 M Ag+ if the same amount of current were used?arrow_forward
- Bromine is obtained from brine wells. The process involves treating water containing bromide ion with Cl2 and extracting the Br2 from the solution using an organic solvent. Write a balanced equation for the reaction of Cl2 and Br. What are the oxidizing and reducing agents in this reaction? Using the table of standard reduction potentials (Appendix M), verify that this is a product-favored reaction at equilibrium.arrow_forwardIron(II) ion undergoes a disproportionation reaction to give Fe(s) and the iron(III) ion. That is, iron(II) ion is both oxidized and reduced within the same reaction. 3 Fe2+(aq) Fe(s) + 2 Fe3+(aq) (a) What two half-reactions make up the disproportionation reaction? (b) Use the values of the standard reduction potentials for the two half-reactions in part (a) to determine whether this disproportionation reaction is product-favored at equilibrium. (c) What is the equilibrium constant for this reaction?arrow_forwardCopper(I) ion disproportionates to copper metal and copper(ll) ion. (See Study Question 99.) 2 Cu+(aq) Cu(s) + Cu2 + (aq) (a) What two half-reactions make up the disproportionation reaction? (b) Use values of the standard reduction potentials for the two half-reactions in part (a) to determine whether this disproportionation reaction is product-favored at equilibrium. (c) What is the equilibrium constant for this reaction?
