Question

If entropy and enthalpy both change is positive which make this process spontaneous
?

Answer 1

Explanation:

Let us consider the equation for gibbs free energy

ΔG=ΔH−TΔS

Where,

δH is enthalpy change (KJmol

−1

)

T is absolute temperature (K)

ΔS is entropy change (JK

−1

)

For a reaction to be considered spontaneous ΔG<0

Therefore,

ΔH−TΔS<0

ΔH<TΔS

or

T>ΔHΔS
