How can I calculate Gibbs free energy at different temperatures?

1 Answer

#G=H-TS#
#Delta G=Delta H-TDelta S-SDeltaT#

For a particular value of T one can calculate the Gibbs free energy using the above formula.
H=Enthalpy
S=Entropy
The formula can be modified in accordance with the type of data given.
#H=U+PV#
#H=q_(rev)+w+PV#
#rArr Delta H= TDeltaS-PDeltaV+(PDeltaV+VDeltaP + DeltaPDeltaV)#
#rArr DeltaG=VDeltaP + DeltaPDeltaV -SDeltaT#
