Homework Help: chemistry

Posted by Anonymous on Tuesday, October 28, 2008 at 8:24pm.

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?
