The change in entropy for the following transformations is respectively: (+ indicates increase, - indicates decrease and 0 indicates no change) (i) $\mathrm{SO_2Cl_2(g)} \xrightarrow{\Delta} \mathrm{SO_2(g) + Cl_2(g)}$ (ii) $\mathrm{nCH_2{=}CH_2(g)} \xrightarrow{\text{Catalyst}} \mathrm{[-CH_2-CH_2-]_n(s)}$ (iii) $\mathrm{I_2(s)} \xrightarrow[\text{1 atmosphere}]{\Delta} \mathrm{I_2(V)}$ (iv) Adiabatic reversible expansion of an ideal gas
