1.	Change in entropy is negative forA. Bromine`(l)to`Bromine`(g)`B. `C(s)+H_(2)O(g)toCO(g)+H_(g)`C. `N_(2)(g,10 atm)N_(2)(g,1 atm)`D. `Fe(1 mol e,400 K)toFe(1 mol e,300 K)`
Answer» Correct Answer - D The gaseous phase have more entropy and thus `DeltaS` is +ve in (a) and (b). Alos decrease in pressure increase disorder and thus `DeltaS` is `+ve` in (c). In (d)the disorder decrease in solid state due to decrease in temperature. Thus `DeltaS=-ve`
