Question
Equal volumes of 0.00150M FeCl3 and 0.00200M NaSCN were mixed together and reacted according to the equation:
Fe3+ + SCN- <--> FeSCN2+
The equilibrium concentration of FeSCN 2+ was 1.40 x 10^-4 M
Calclulate the equilibrium constant for the reaction.
I got 55.3...is that right? or do you have to use the "equal volumes" part of the question in some way?

Answers
I think you must do an ICE chart and half the concentrations of Fe^+3 and SCN^- to start.
thanx..other people were saying that as well
