Thank you

Answer 1

Given endothermic reactions dala+202(g) → 2 doz (8) we know that in endothermis reaction energy is supplied to the reaction so enthalpy of reaction CaHaxn) is Positive Live Altran 70 now, Here in above reaction number of gasseous Product is less than the gasseous reactantr so randomness of product decreases and hence entropy of reaction (asant is negative inelosancor

we know that ДС, - он - ТДs Aaron - A Horn-Tasoon since A Hoxn >o so, atran = (tore? and abren co so, Asran =(-ove but second term (TASxnl is already negative so if asoon is a negative (-) thay term Tasy will be positive (t) Bror C-TASrana - T-(-ason) = + Taran) Hence, if a Hran is positive and second term is also positive in above equation so surando le A Gran is positive I we know that entropy is measure of randomness of particles. As Tenperature increases randomness increases so entropy also increases. it temperature (1) decreases randomness decreases iso entropy decreases. Hence. A universe Colow T 70 high T
