Please answer these questions on your Page 10 (a) ( For the reaction A(aq) + 2 B(aq) ⇒ 2 C(aq), the equilibrium concentrations of A(aq), B(aq), and C(aq) are 0.444 M, 0.333 M, and 0.666 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 AG value equal to -7.777 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 27.7 mL of a 0.333 M solution of Ba(OH)₂(aq). What was the original concentration of H3PO4(aq)?
