The change in entropy for the following transformations is respectively: (+ indicates increase, - indicates decrease and 0 indicates no change) (i) $\mathrm{SO}_{2} \mathrm{Cl}_{2}(\mathrm{g}) \xrightarrow{\Delta} \mathrm{SO}_{2}(\mathrm{g})+\mathrm{Cl}_{2}(\mathrm{g})$ (ii) $\mathrm{nCH}_{2}=\mathrm{CH}_{2}(\mathrm{g}) \xrightarrow{\text { Catalyst }}\left[-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\right]_{\mathrm{n}}(\mathrm{s})$ (iii) $\mathrm{I}_{2}(\mathrm{s}) \xrightarrow[1 \text { atmosphere }]{\Delta} \mathrm{I}_{2}(\mathrm{V})$ (iv) Adiabatic reversible expansion of an ideal gas
