Problem

For each case below, use the given entropy changes to decide whether the process is reversible or irreversible: a. (a)

\Delta S_{\text{sys}} = +5\,\text{J K}^{-1}

\Delta S_{\text{surr}} = -5\,\text{J K}^{-1}

b. (b)

\Delta S_{\text{sys}} = +2\,\text{J K}^{-1}

\Delta S_{\text{surr}} = -1\,\text{J K}^{-1}
