Standard molar entropy (9.53)

Postby Lucia H 2L » Wed Feb 07, 2018 10:59 pm

How do you find the standard molar entropy of the reaction of NH3(l) --> NH3(g)? The tables in the book show the standard molar entropy for the gas, but nothing for the liquid. Is it assumed we can use the aqueous solution?

If you look at Table 9.1 (page 328) in the book, the last column gives us the standard entropy of vaporization for a bunch of liquid substances (ammonia included!). I think we'd just use that because we're looking specifically at vaporization reactions.
