7. For OH-(aq), Sº is -10.7 J/mol-K, which is negative. Which comment below is correct? The hydroxide ion must be perfectly symmetrical and tightly organized. Sº is a relative value: This is an artifact since absolute entropy can't be negative. This must be a mistake since there can't exist fewer than no possibilities. The hydroxide ion is an unusual ion compared with all other aqueous ions.

Choose the correct answer out of the three options: Suppose an isolated system undergoes a change and the result is that parts of the system become more disordered. It could be said that such a process (increases/decreases/does not change) the entropy of the system. The entropy change of the system is considered to be (positive/negative/zero).
