If E cell is negative, does that indicate that the reaction is not favorable? Can there every be a negative value for E cell?

The reaction is favorable when the E cell is positive. In return, a reaction is favorable when deltaG is negative (as when E cell is positive, deltaG is negative).

As Dr. Lavelle explained in class today, the reaction is favorable if Ecell is positive, because that means that delta G is negative. When delta G or Gibb's free energy is negative, that means the reaction is favorable.
