(10/18/00) 59. Is it true that when delta Go is positive, then the reaction goes to the left?
Tends to go left. The actual direction under any particular set of circumstances will can be influenced by the concentrations.

Delta Go is dependent on direction; is that true for delta G as well?
The dependency goes the other way round: direction is determined by the delta G's. Delta Go specifies a tendency to go in a specific direction (i.e., defines the direction under standard conditions). Delta G defines the direction period (i.e., for the conditions under consideration).
