(10/18/00) 60. Is it true that when delta Go is positive, Keq MUST be less than 1 as you will see much more reactant than product?
Yes, less than one; and yes, at equilibrium.

In problem 4-2, what is the relation of Keq to the concentrations of starting material? Keq is independent of starting concentrations. Delta G-zero and Keq are both constants, defined independently of starting concentrations. Delta G is different -- it depends on what concentrations you start with. One point of the question is to drive home that Keq doesn't change if you change starting concentrations.
