 P: 45 I got these two questions i have no idea how to do (i have answers, but no soln's) 1. Given that the affinity constatn Keq for rxn A+B=AB is 5x10^6 and the concentration of free molecules at equillibrium are Afree = 1x10^-4 and B = 1x10^-8, what is the ration of AB to A at equillibrium ans: 0.05 : 1 2. What is the Delta G for the forward reaction x <-> y. Given R = 1.98x10^-3 kcal/molK T = 298K K'eq = 7.5 (ans: -1.18kcal/mol)

 P: 16 Use $$K_{eq} = \frac{[AB]}{[A][B]}$$

you dont understant.. its not my hw. just tell me the formula for delta g, thats all i need
 HW Helper Sci Advisor P: 1,767 $$K= \frac{[x]}{[A-x][B-x]}$$ You should be able to find such equations in the text by yourself, the're all listed explicitly. ...since it's urgent
