Document Summary

Change in g vs. change in g^0: contd gibbs free e, change in g vs. change in g^0, q (reaction quotient) vs. k (equilibrium constant) Change in s < 0 decrease s (kj/k) Not spontaneous in forward direction under standard state conditions only. Predict direction of spontaneity with q and k. Steps: compare q to k, compare k to 1. Change in g = 0 ; q = k. Depends on proportions of the reaction mixture (ex. Change in g^ 0 with one value (eqm properties) Change in g^0 values = product (change in. G^0 products) - reactant (change in g^0 reactants) Note: nature tends to increase the distribution of lower e eqm near r/p with. Note: dip in gibb"s free e = extra combination of mixing r + p (temporary increase in possibilities) Different x-axis labelling (how much e is required to change through. Change in g^ double dagger or free e of.
