According to Gibb's free energy, ΔG=ΔH−TΔS
Reaction is non spontancous i.e. ΔG>0 at 298K.
As the temperature increases from 298K to 350K.
The reaction becomes spontaneous i.e. ΔG<0.
ΔG=ΔH−TΔS
ΔG<0
When ΔH and ΔS are +ve then, ΔG will be positive till ΔH>TΔS.
When the temperature is increased further ΔH becomes less than TΔS i.e.
ΔH<TΔS and ΔG becomes −ve.
Thus, reaction becomes spontancous.
