Equilibrium Concentrations for a Simple Addition Reaction?

Question

At a certain temperature K = 1.10×103 for the reaction:

Fe3+(aq) + SCN-(aq)= FeSCN2+(aq)

1.90×10-1 mol of Fe(NO3)3 is added to 1.27 L of 1.57×10-2 M KSCN.

Neglecting any volume change and assuming that all species remain in solution--:

Calculate the equilibrium concentration of Fe3+ (in mol/L).



Calculate the equilibrium concentration of SCN- (in mol/L).


Calculate the equilibrium concentration of FeSCN2+ (in mol/L).

Answer 1

Please specify whether "FeSCN2+" in:
Fe3+(aq) + SCN-(aq)= FeSCN2+(aq)
is actually Fe(SCN)2(+) or FeSCN(2+)

Answer 2

26.B,by means of fact it may merely be desperate by way of employing experiments 27.A , by means of fact the degree of the entire fee regulation won't exchange 28. C , by means of fact it makes the reaction swifter to overcome the activation capability
