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 \({\text{J}}\,{{\text{K}}^{ - 1}}{\text{mo}}{{\text{l}}^{ - 1}}\)?
