What does a positive delta H tell about reaction?
This is an endothermic chemical reaction.
What does a negative H tell about a reaction?
The reaction is exothermic.
Under what conditions is G for a reaction always positive?
When H is positive and S is negative
How do you know if a reaction is entropy driven enthalpy driven or driven by both enthalpy and energy?
If the ∆H is positive and the ∆S is positive, then the reaction is entropy driven. If the ∆H is negative and the ∆S is negative, then the reaction is enthalpy driven. If ∆H is positive and ∆S is negative, then the reaction is driven by neither of these. If ∆H is negative and ∆S is positive, then the reaction is driven by both of these.
How is temperature affect the spontaneity of a reaction with positive H and S?
∆G = ∆H - T∆S and ∆G has to be negative for the reaction to be spontaneous. So, ultimately the effect of temperature will depend on the value of ∆H. If ∆H is negative, and ∆S is positive, then temperature won't matter, and reaction will be spontaneous. If ∆H is positive, and ∆S is positive, then a high temperature will favor spontaneity. If ∆H is negative and ∆S is negative, then a low temperature will favor spontaneity. So, the answer to your question is the higher the temperature the more likely the reaction will occur spontaneously.

According to the Gibbs free energy equation G H - TS when is a reaction always spontaneous?
when H is negative and S is positive
How will temperature affect the spontaneity of reaction with positive H and S?
A high temperature will make it spontaneous.
How will the temperature affect the spontaneity of a reaction with positive h and s?
A high temperature will make it spontaneous.
