Equation
ЁЯФ║G = ЁЯФ║H - TЁЯФ║S ( T is in kelvin, + 273)
-+
At all temperature
++
At high temperature
+-
Non-spontaneous
ЁЯФ║G < 0
Reaction is feasible and can take place spontaneously.
ЁЯФ║G > 0
Reaction is not feasible and cannot take place spontaneously.
SPECIAL CASE
Reactiom must have energy [ >/= ] Activation energy,Ea. for a reaction to occur.
ЁЯФ║G = 0
Reaction is equilibrium. ( melting, freezing , boiling)
--
At low temperature
