For question 9.15 the change in entropy for freezing of H20 at 0.00C uses a negative deltaH of fusion in the solution manual but this value is not negative in the chart 8.3. Just to clarify, is it negative here because the reaction is going from liquid to ice so the change in entropy is negative?
Yes, it is because you are going from liquid to ice which is the opposite of fusion. You could also think of this in terms of the molecules gaining or losing heat since the molecule is going from liquid to ice, it is losing heat so deltaH would be negative.
