How will temperature affect the spontaneity of a reaction with positive H and S? A. It will be spontaneous only at T = H/S.
B. Changing the temperature will not affect spontaneity.
C. A low temperature will make it spontaneous.
D. A high temperature will make it spontaneous.

D.A high temperature will make it spontaneous.

Explanation:

we know that

Δ G = Δ H - TΔS

For spontaneous reaction

Δ G should be negative . If Δ G = 0

Δ H =  TΔS

T =   Δ H / Δ S

At temperature above this T , Δ G becomes negative if Δ S and ΔH are  positive .

So at a  high temperature will make it spontaneous.

D. A high temperature will make it spontaneous.
