Question

A process will be spontaneous at all temperatures if : (A) Δ H > 0 and Δ S < 0 (B) Δ H < 0 and Δ S > 0 (C) Δ H > 0 and Δ S > 0 (D) Δ H < 0 and Δ S < 0

Δ G = Δ H - T Δ S for spontaneous process at all temp. Δ G < 0 and it is possible when Δ H < 0 and Δ S > 0.

Q. A process will be spontaneous at all temperatures if :

$Δ H > 0$ and $Δ S < 0$

$Δ H < 0$ and $Δ S > 0$

$Δ H > 0$ and $Δ S > 0$

$Δ H < 0$ and $Δ S < 0$

$Δ G = Δ H - T Δ S$
for spontaneous process at all temp. $Δ G < 0$ and it is possible when $Δ H < 0$ and $Δ S > 0$ .

Q. A process will be spontaneous at all temperatures if :

ΔH>0 and ΔS<0

ΔH<0 and ΔS>0

ΔH>0 and ΔS>0

ΔH<0 and ΔS<0

ΔG=ΔH−TΔS for spontaneous process at all temp. ΔG<0 and it is possible when ΔH<0 and ΔS>0.

$Δ H > 0$ and $Δ S < 0$

$Δ H < 0$ and $Δ S > 0$

$Δ H > 0$ and $Δ S > 0$

$Δ H < 0$ and $Δ S < 0$

$Δ G = Δ H - T Δ S$
for spontaneous process at all temp. $Δ G < 0$ and it is possible when $Δ H < 0$ and $Δ S > 0$ .
