find eVal and Kc please

7. IF (this is strictly hypothetical to give you practice following the process for calculations - the values are NOT similar to what your measured values should be for this experiment!!) your standard solution of Fe(SCN). was 0.0500 M, and had an absorbance of .842, AND your first trial on a sample of unknowg Fe(SCN) had an absorbance of .523; what is the [Fe(SCN)''] for the unknown in this trial? 142 abs: 0.som 84.2 obg: 5.00 A- A2 CI (652 31.842) (10.500 M) ..03159M 8. If (again hypothetical) initial concentrations of Fe and SCN for the trial reaction yielding the results listed in question #7 were 0.210 M and 0.150 M, respectively, complete the ICE table below and use the information obtained (in question # 7) to determine a "hypothetical" value for K..
