yes the statemenrt is not true .
we know that ×G =×H - T×S
where ×represents delta
delta h -ve ,delta s +ve always spontaneous
h=+ve s=-ve non spontNeous at lll temperature
h=+ve s=+ve spontaneous at high temperatue
h=-ve s=-ve zpontaneous at low temperarure
in the reaction of the formation of NO and No2 the standard free energy change is 87.6kj/mole and 51.3kj/mole .yet we see the formation of NO and NO2.
N2 + O2----2NO
NO + .5 O2------NO2
thus we see that although delta g is positive yet the reaction occurs
thanks and regards
