Answer 1

Answer #1

Ans- T> -446 K

We have ∆G = ∆H - T∆S.

For spontaneous process ∆G<0

So ∆H/∆S < T

Therfore ∆H/∆S = 111000/-249 K= -446K.

Therefore T> -446 K for spontaneous reaction

P.S : Please do give a thumbs up since we as an take pain and take our time out by typing answer in lucid language and putting best of our knowledge at your doorstep.
Thank you
