Question
For a chemical reaction, at 298 Kelvin, the H = (+) and the S = (-). Is the reaction spontaneous or nonspontaneous at this temperature?
The reaction is always spontaneous, regardless of the temperature.
The reaction is always nonspontaneous, regardless of the temperature.
The values of the H and the S would need to be known. The value of G would need to be calculated, since H is favored and S in not favored.

A.The reaction is always spontaneous, regardless of the temperature.
B.The reaction is always nonspontaneous, regardless of the temperature.
C.The values of the H and the S would need to be known. The value of G would need to be calculated, since H is favored and S in not favored.
D.The values of the H and the S would need to be known. The value of G would need to be calculated, since H is not favored and S is favored.
Explanation / Answer
G = H - T* S
Since H is positive and S is negative, G will surely be positive
So, reaction will be non spontaneous always
