Given the following information at 25°C, Calculate AS° for the reaction:
SO3(g) + H₂O(1) -H₂SO4(1).
(Hint: Because AS° is a state function (like AHº) you can use a table to calculate it in
the same way. This means you should add up all the entropy for the products (times
the number of each) and subtract all the entropy for the reactants.)
