Question

Underwhat conditions a reaction be spontaneous if both h and s are positive

Answer 1

Answer:

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
