Consider the following reaction at 315 K: 1 A (aq) + 2 B (aq) 1 C (aq) + 1 D (aq) An experiment was performed with the following intitial concentrations: [A]j = 1.45 M, [B]j = 2.15 M, [C] = 0.53 M, = 0.27 M. The reaction was allowed to proceed until %3D [D]i equilibrium was reached at which time it was determined that [A] = 0.65 M. What was the maximum amount of work that could have been performed as the reaction began? Maximum amount of work performed as the reaction began (in kJ)=
