In which of the following processes, the sign of change in entropy is different from the other three

A liquid crystallises into a solid $\stackrel{}{\to }\Delta S=-ve$

Temperature of a crystalline solid is raised from OK to 115 K$\Delta S\stackrel{}{\to }+ve$

$2NaHC{O}_{}\left(s\right)\to N{a}_{2}C{O}_3\left(s\right)+C{O}_2\left(g\right)+H_{2}O\left(g\right)$ $\Delta S\stackrel{}{\to }+ve$

$H_2\left(g\right)\to 2H\left(g\right)$$\Delta S\stackrel{}{\to }+ve$
