Question
In which reaction is delta S expected to be positive? A) CH3OH(g) + 3/2O2(g) -> CO2(g) + 2H2O(l) B) H2O(l) -> H2O(s) C) 2O2(g) + 2SO(g) -> 2SO3(g) D) I2(g) -> I2(s) E) None of these In which reaction is delta S expected to be positive?

the reaction having delta S positive is given below
E) None of these
becasue in case of A number of moles in gas phase is decreasing as H2O is in liquid form.
B liquid to soild so delta S in negative
C number of oles decreasing so deltaS is negative
D gas to solid so deltaS is negative.
