The value isn't significant, but ∆G must be negative for a spontaneous reaction.

How can a reaction with negative value of Delta G be described?
As spontaneous
How do you know if a reaction is spontanious?
If delta G value is minus,it is spontaneous
A chemical reaction has a positive ΔH value and a positive ΔS value Under what conditions is the reaction spontaneous?
The reaction is spontaneous only at high temperatures.
What is the difference between a reaction that happens spontaneously and a reaction that doesn't?
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.
How does the Gibbs free energy predict spontaneity?
It tells if the reaction will process spontaneously or not

A chemical reaction has a positive H value and a positive S value Under what conditions is the reaction spontaneous?
the reaction is always spontaneous :) youre welcome =D i just took this on apex, the correct answer is the reaction is spontaneous only at high temperatures.

What value should the heat of the reaction have in a spontaneous reaction?
It can be + or - depending on the value of the entropy (∆S). Recall, that ∆G = ∆H - T∆S and for a spontaneous reaction, ∆G must be negative, so you can see how this will depend on the values and signs of both enthalpy and entropy.

How does Gibbs free energy predict spontaneous?
If G < 0, the reaction is spontaneous.
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
How do you determine whether a reaction is spontaneous or non spontaneous?
The first of two factors that determine whether a reaction is spontaneous or non-spontaneous is entropy. The second is energy. For a reaction to be spontaneous, it must have both of these factors.

If G < 0, the reaction is spontaneous.

Is spontaneous reaction exo or endo?
Reactions are described by this equation: GD = HD - TDS where D = delta for change in values. GD < 0 spontaneous HD < 0 exothermic ; HD > 0 endothermic The first equation is Gibbs free energy. When G is negative, the reaction is spontaneous. In contrast, a positive number G is non spontaneous. The interesting thing is that spontaneous reactions can be EITHER exothermic and endothermic. Lets look at this: lets assume HD has a value of 100. This means TDS would have to be bigger than 100 in order to make GD a negative number. An endothermic reaction which has a positive H can still be exothermic. Here's another way to pose your question: Is an exothermic reaction spontaneous? Always. Is an endothermic reaction spontaneous? This can be either.
