Question

What are the values of `DeltaH` and `DeltaS` for the change from gaseous to liquid `H_2O`?

Answer 1

For the process... `H_2O(g) rarr H_2O(l)+Delta`

Explanation:

AS written, `DeltaH` should be negative (i.e. heat should be a product of the reaction), and ALSO `DeltaS^@` should be NEGATIVE, because we go from a gaseous phase to a condensed phase, which minimizes the probability of disorder.

As to actual values for the processes, you will find these in your text.
