Classify the possible combinations of signs for a reaction's ∆H and ∆S values by the resulting spontaneity.
A) Spontaneous as written at all temperatures.
B) Spontaneous in reverse at all temperatures.
C) Spontaneous as written above a certain temperature.
D) Spontaneous as written, below a certain temperature.
1) ∆H = + // ∆S = +
2) ∆H = - // ∆S = +
3) ∆H = - // ∆S = -
4) ∆H = + // ∆S = -
I'm beyond confused. Please help!

Thanks page
Thanks Paige.
Thanks Paige! :D
我叼你妈的,一个个都是谜语人?
i agree with 你爸爸

Spontaneous as written at all temperatures: delta H=- and delta S=+
Spontaneous in reverse at all temperatures: delta H=+ and delta S= -
Spontaneous as written above a certain temperature: delta H=+ and delta S=+
Spontaneous as written below a certain temperature: delta H=- and delta S= -
Both are wrong. The wiki-link is correct.
