Want this question answered?
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.
Spontaneous
If you hold a match to the paper, then yes, the reaction is 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.
The value isn't significant, but ∆G must be negative for a spontaneous reaction.
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 only at high temperatures.
As spontaneous
If delta G value is minus,it is spontaneous

the negative value for a standard potential indicates that the reaction is not spontaneous.
B
Spontaneous
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.
If you hold a match to the paper, then yes, the reaction is spontaneous.
