Question
For a reaction to be spontaneous at all temperatures
Options
A.ᐃG - ve, ᐃH + ve and ᐃS + ve
B.ᐃG + ve, ᐃH - ve and ᐃS + ve
C.ᐃG - ve, ᐃH - ve and ᐃS - ve
D.ᐃG - ve, ᐃH - ve and ᐃS + ve
Solution
Since ᐃG = ᐃH - TᐃS If ᐃG is negative, ᐃH negative and ᐃS is positive, then the reaction will be spontaneous at all temperatures.
