Determination of equilibrium constant keq
WebOct 26, 2016 · Using this value, I used the equation for the K constant of an equilibrium: K = [ F e S C N X 2 +] [ F e X 3 +] [ S C N X −] K = 6.39 ⋅ 10 − 5 0.002 2 K = 15.975 This did not turn out to be the correct answer, but I'm not sure why. I suspect the concentrations for the two reactions are not correct since the volumes are also given. equilibrium http://xmpp.3m.com/spectrophotometric+determination+of+an+equilibrium+constant
