Question

How can I calculate Gibbs free energy at different temperatures?

Answer 1

`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`
