Title: Equilibrium constant
Post by: FirstStryke on October 26, 2005, 12:02:27 PM

Hi I am working on a lab at the moment and am having difficulty in determining the equilibrium constant.  For one of them I have found the percent transmittance to be 90.5%.  However I am finding it difficult to calculate the K_eq with the formula A=(?b)c .  What steps am I missing???  Please help.  I have figured that ?b = 6.08e³M^-1, and that absorbtivity is 0.0433514.
