Question

If Δ H and Δ S are positive for a reaction, the reaction will be spontaneous only when (A)  TΔ S=Δ H  (B)  TΔ S>Δ H  (C)  TΔ S<Δ H  (D)  TΔ S is negative

Δ G=Δ H-TΔ S for spontaneity, Δ G°<0 and this occurs when TΔ S>Δ H

Q. If $Δ H$ and $Δ S$ are positive for a reaction, the reaction will be spontaneous only when

$T Δ S = Δ H$

$T Δ S > Δ H$

$T Δ S < Δ H$

$T Δ S$ is negative

$Δ G = Δ H - T Δ S$ for spontaneity, $Δ G^{\circ} < 0$ and this occurs when
$T Δ S > Δ H$

Q. If ΔH and ΔS are positive for a reaction, the reaction will be spontaneous only when

TΔS=ΔH

TΔS>ΔH

TΔS<ΔH

TΔS is negative
