Based on the calculated values of Kc for each reaction stoichiometry, which reaction is the valid one?
Fe(aq)3+ + SCN(aq)- FeSCN(aq)2+ The average value of Kc: 369.10
Fe(aq)3+ +2 SCN(aq)- Fe(SCN)2(aq)+ The average value of Kc: 988999.02
Briefly explain your conclusion. Compare the percent difference between the average value and the individual measurements. What does this tell you about the two possible stoichiometries? Do these reactions give consistent values of Kcfor different initial reaction conditions?
