11. 298K 時，下列反應中 entropy 值增加最多的是：
(A) \( \text{H}_2(\text{g}) + \text{Br}_2(\text{l}) \rightarrow 2\text{HBr}(\text{g}) \)
(B) \( 2\text{N}_2\text{H}_4(\text{l}) + \text{N}_2\text{O}_4(\text{l}) \rightarrow 3\text{N}_2(\text{g}) + 4\text{H}_2\text{O}(\text{l}) \)
(C) \( \text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) \rightarrow 2\text{NH}_3(\text{g}) \)
(D) \( 2\text{N}_2 + \text{O}_2(\text{g}) \rightarrow 2\text{N}_2\text{O}(\text{g}) \)
(E) \( \text{NH}_4\text{Cl}(\text{s}) \xrightarrow{\text{H}_2\text{O}} \text{NH}_4^+(\text{aq}) + \text{Cl}^-(\text{aq}) \)
