The usage of different sign combinations of standard enthalpy change and standard entropy change in predicting the spontaneity of reactions has to be explained. Concept introduction: Free energy: Free energy is measured by subtracting the product of temperature and entropy from the enthalpy of a system. G = H - TS where, G - free energy; H - enthalpy S - entropy and T -temperature . Relationship between ΔG o , ΔH o and ΔS o is given by ΔG o = ΔH o - TΔS o where, ΔG o - standard free energy change; ΔH o - standard enthalpy change ΔS o - standard entropy change and T - temperature Spontaneous process: The chemical or physical change can takes place by itself without the help of surroundings are called as spontaneous process. To explain: the different sign combinations of standard enthalpy change and standard entropy change

Concept introduction:
Free energy:
Free energy is measured by subtracting the product of temperature and entropy from the enthalpy of a system.
G=H-TSwhere,G-freeenergy;H-enthalpyS-entropy and T-temperature.
Relationship between ΔGo,ΔHoandΔSo is given by
ΔGo=ΔHo-TΔSowhere,ΔGo-standardfreeenergychange;ΔHo-standardenthalpychangeΔSo-standardentropychange and T-temperature
Spontaneous process:
The chemical or physical change can takes place by itself without the help of surroundings are called as spontaneous process.
To explain: the different sign combinations of standard enthalpy change and standard entropy change
can you draw each step on a piece of a paper please this is very confusing to me
