Question
Question :
(a) For the reaction 2 A(aq) ⇋ B(aq) + C(aq), the value of ΔGo is 2.21 kJ at 25.0oC. If the initial concentrations of A(aq), B(aq), and C(aq) are respectively 0.418 M, 0.343 M, and 0.229 M, what will be the concentration of A(aq) when we reach equilibrium at 25.0oC?
(b) To a 88.8 mL aqueous solution of NaOH, we add an excess of Fe(NO3)3 and produce 0.262 g of Fe(OH)3(s). What was the original pH of the NaOH solution?
