18, You are trying to find the equilibrium constant for the reaction At(aq) + B (aq) AB(aq) wherethe compound AB has a strong absorbance at 520 nm, and the ions do not absorb light at thatwavelength. The following data for concentration versus absorbance was collected in a calibrationrun:[AB] (x 104 M)AB(absorbance)1.000.0842.000.1673.000.2514.000.3375.000.421In an actual experiment, [A'l = 0.0160 M and [Bl = 0.0100 M. The equilibrium transmittanceof the solution was 51.0%. Since the relation between %T (percent transmittance) and A (absorbance)is A=2- log(%T), the absorbance of the solution at equilibrium is about 0.292Can one use the data to find the equilibrium constant Ke for the reaction? Give a generaldescription of how, if possible, or why not, if not possible.
