ΔGo = ΔHo - T*ΔSo
For reaction to be spontaneous, ΔGo should be negative
Case 1: spontaneous at high temperature
ΔHo is positive
ΔSo is positive
ΔGo will be negative at high temperature.
Case 2: non spontaneous at all temperature
ΔHo is positive
ΔSo is negative
ΔGo will always be positive
Case 3: spontaneous at all temperature
ΔHo is negative
ΔSo is positive
ΔGo will always be negative
Case 4: spontaneous at low temperature
ΔHo is negative
ΔSo is negative
ΔGo will be negative at low temperature.
A)
Reaction is spontaneous at high temperature
So,
ΔHo is positive
ΔSo is positive
B)
It is spontaneous at all temperatures.
So,
ΔHo is negative
ΔSo is positive
C)
The reaction is exothermic.
Spontaneity information are not there.
So,
ΔHo is negative
ΔSo is unknown
