The reduction of iron(III) oxide (Fe,0,) to pure iron during the first step of steelmaking, 2 Fe,0,(s) → 4Fe(s) + 30, (g) is driven by the high-temperature combustion of coke, a purified form of coal: C(s) + 0,(g) → Co, (g) Suppose at the temperature of a blast furnace the Gibbs free energies of formation AG, of CO, and Fe, O, are -428. kJ/mol and -833. kJ/mol, respectively. Calculate the minimum mass of coke needed to produce 2000. kg of pure iron. Round your answer to 2 significant digits. kg Explanation Check

Calculate the change in Gibbs energy for each of the sets of ΔrH∘, ΔrS∘, and T.

In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 72.0 °C and constant total pressure. Then, she measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of her measurements are shown in the table. Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then, decide whether, under the conditions the engineer has set up, the reaction is spontaneous, the reverse reaction is spontaneous, or neither forward nor reverse reaction is spontaneous because the system is at equilibrium.
