The reaction between but-1-ene and water vapour produces butan-1-ol.

$${{\text{C}}_4}{{\text{H}}_8}{\text{(g)}} + {{\text{H}}_2}{\text{O(g)}} \to {{\text{C}}_4}{{\text{H}}_9}{\text{OH(l)}}$$

The standard entropy values ${\text{(}}{S^\Theta }{\text{)}}$ for but-1-ene, water vapour and butan-1-ol are 310, 189 and ${\text{228 J}}\,{{\text{K}}^{ - 1}}{\text{mo}}{{\text{l}}^{ - 1}}$ respectively. What is the standard entropy change for this reaction in ${\text{J}}\,{{\text{K}}^{ - 1}}{\text{mo}}{{\text{l}}^{ - 1}}$?
