A reaction XXX is exergonic and endothermic under standard conditions; what must be true of XXX under these conditions?

* I do not understand this at all.

*wouldn't it be delta G = H - TdetaS
- = + - +
*then you get entropy decreasing NOT increasing?

You answered this one yourself. Your sign for entropy is positive (the last + sign): Entropy is increasing. The entire term containing entropy (-TdletaS) is negative, but the change in entropy itself is positive - also simply called an increase in entropy.
