Want this question answered?
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.
Spontaneous
If you hold a match to the paper, then yes, the reaction is spontaneous.
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)
If G < 0, the reaction is 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.

The reaction is spontaneous.
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
The value isn't significant, but ∆G must be negative for a spontaneous reaction.

spontaneous redox reaction
The reaction is spontaneous only at high temperatures.
If G < 0, the reaction is spontaneous.
