Question

8. The second law of thermodynamics states that A) Delta E=g+w B) Delta H^ 0 rrn =Sigma nDelta H^ f(products)-Sigma mDelta H^ f(reac reactants) C) for any spontaneous process, the entropy of the universe increases D) the entropy of a pure crystalline substance is zero at absolute zero E) Delta S=q rcv /T at constant temperature

D) zero E) the same as the energy, E 8. The second law of thermodynamics states that A) AE - 9+ w B) AHørxn = nАHºf (products) - mAH®f (reactants) C) for any spontaneous process, the entropy of the universe increases D) the entropy of a pure crystalline substance is zero at absolute zero E) AS = grey/T at constant temperature

Answer 1

Solution :- AS = Assystem + AS surroundy for an irreversible fross AS systems + AS surroundry > since almost all process of nature are Irreversible in nature . AS Systems + AS surrondly >o fos universe - "Entropy of universe is continously increasing" This is statement of seeend law of thermo- - dynamics in terms af entropy. ... The second law of thermodynamics Stats that (C) for any spontaniors process, the entrofy og universs L increases * A 3) D) statiment af 1st Law as thermodynam's Enthalfy Change of reaches Entroly change in isothermal reversible frours
