Equilibrium Frustration....... Ive been going over a chem paper and cannot seem to get any of the multiple choice given answers, the question is as follows, The free energy change for the formation of the complex ion [tex] AlF_6^3-[/tex] is -140. kJ at 25ºC. What is the equilibrium constant, K, for the reaction? Ive got: deltaG = -RT InK hence, -140 = -(8.3145)(298.15) InK hence, InK = -140 + (8.3145)(298.15) InK = 2338.0 but this gives a value of K=0, which cant be correct, or if it is, the answer does not appear in the choices in my paper. Any ideas, Can anyone see where im going wrong? Thanks for your time.
