Q1. What if the equation for the equilibrium were:
How would the expression for the Kc be written?
Fe3 + 2SCN --> Fe(SCN)2
Q2 If the reaction in question 1 is correct, the concentrations of Fe3+ at equilibrium in each
sample would be the same as you calculated in part 2 of the calculations section. But the
values for the equilibrium concentrations of SCN- would change. They would be
calculated as follows:
Why is that? (Assume that the Spec 20 measurements still gave correct values for the
concentration of the product
Explanation / Answer
Kc
It is not correct equation
It should be like this
Fe3 + + 3SCN- --> Fe(SCN)3
and Kc would be
Kc=
Kc
It is not correct equation
It should be like this
Fe3 + + 3SCN- --> Fe(SCN)3
and Kc would be
Kc=
