For the reaction 2 A(aq) <---> B(aq) + C(aq), the standard Gibbs free enthalpy change is 1.69 kJ at 25oC. The initial concentration of A(aq) is 0.549 M, the initial concentration of B(aq) is 0.327 M, and the initial concentration of C(aq) is 0.234 M. What would be the concentration of A(aq) (in mol/L) once we attain equilibrium (we are still at 25oC)?

A sample of a concentrated fluorescent reagent was serially diluted with three steps using a variable volume 100 to 500 μL micropipetor and 10.00 mL Class A volumetric flasks. The concentrated reagent had a fluorescent signal of 653.4 and the diluted sample produced 0.057 fluorescence units. Unfortunately the steps followed for the dilution were lost. What were those steps?
