Thermodynamic.. First understand..Terminology Enthalpy (dH), Entropy (dS), Free Energy (dG), Temperature (T) As formula dG=dH-TdS As per this formula, Temperature increases, Free Energy Decrease. (Consider d as Delta, sorry I couldn't write Delta sign)

First understand..Terminology

Enthalpy (dH), Entropy (dS), Free Energy (dG), Temperature (T)As formula

dG=dH-TdSAs per this formula, Temperature increases, Free Energy Decrease.

See lessLet us consider a reactionM(s)+ O2(g)=MO2(s)…..(1)

Here as gaseous phase is involved in reactant side so entropy is more in reactant side.

Now comparing Free energy eqn with a straight line eqn

dG=dH-TdS

Y=C+mX

Slope =m=-dS

According to reaction 1 change in entropy=dS=S(product)-S(reactant) is negative.

As dS is negative,then slope m=-dS is positive. So free energy increases with increase in temperature.

Free energy of any component is related to bond strength between atoms or particles... So as the temperature increasing. Bonds getting weaker.. So as the free energy decrease..
