ALEKS - Rafia Riaz - Learn
A chemical engineer is studying the two reactions shown in the table below.
In each case, she fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 9.0 °C and constant total pressure. Then,
she measures the reaction enthalpy AH and reaction entropy A.S 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.
PbSO₂ (s) + 4H₂O(1) 4H₂O₂ (1) + PbS (s)
2Fe(s) + 3H₂O(l) → Fe₂O₂ (s) + 3H₂(g)
Complete the table. That is, calculate AG for the first reaction and A.S 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.
