For the reaction A(aq) + 2 B(aq) =3 C(aq), the equilibrium concentrations of A(aq), B(aq), and C(aq) are 0.444 M, 0.333 M, and 0.777 M, respectively. If we adjust the concentrations of A(aq) and B(aq) to 0.555 M and 0.222 M, respectively, what concentration of C(aq) will be required to have a ∆G value equal to -5.555 kJ? The temperature is 25.0 ◦C throughout.

Question
(a) For the reaction A(aq) + 2 B(aq) =3 C(aq), the equilibrium concentrations of A(aq),
B(aq), and C(aq) are 0.444 M, 0.333 M, and 0.777 M, respectively. If we adjust the concentrations of
A(aq) and B(aq) to 0.555 M and 0.222 M, respectively, what concentration of C(aq) will be required
to have a ∆G value equal to -5.555 kJ? The temperature is 25.0 ◦C throughout.
(b) To neutralize 25.0 mL of a solution of the triprotic acid H3PO4(aq), we require 18.8 mL
of a 0.555 M solution of Ba(OH)2(aq). What was the original concentration of H3PO4(aq)?
