Determine the entropy change for the reaction given below;

2\text{H}_2(\text{g}) + \text{O}_2(\text{g}) \longrightarrow 2\text{H}_2\text{O}(\text{l})

at 300 K. If standard entropies of

\text{H}_2(\text{g})

\text{O}_2(\text{g})

and

\text{H}_2\text{O}(\text{l})

are 126.6, 201.20 and

68.0 \text{ J K}^{-1} \text{ mol}^{-1}

respectively.
