Answer 1

Answer:

Gibbs free energy-

i) G is defined as H−TS where H and S are enthalpy and entropy of the system respectively T= temperature. Since H and S are state functions, G is a state function.

ii) G is an extensive property while ΔG=G

−G

which is the free energy change between the initial and final states of the system.

iii) G has a single value for the thermodynamic state of the system.

iv) G and ΔG value correspond to the system only.

There are three cases of ΔG in predicting the nature of the process.

a) When ΔG<0, (Negative), the process is spontaneous and feasible.

b) When ΔG=0, the process is in equilibrium.

c) When ΔG>0, (Positive), the process is non-spontaneous and not feasible.

v) ΔG=ΔH−TΔS but according of I law of thermodynamics.

ΔH=ΔE+PΔV and ΔE=q−w

∴ΔG=q−w+PΔV−TΔS

but ΔS−q/T and TΔS=q= heat involved in the process.

∴ΔG=q−w+PΔV−q=w+PΔV

(or) −ΔG=w−PΔV= Network.

The decrease in free energy −ΔG, accompanying a process taking place at constant temperature and pressure is equal to maximum obtainable work.

Network =−ΔG=w−PΔV
