    \[N{{H}_{4}}Cl(s)\xrightarrow{{}}N{{H}_{3}}(g)+HCl(g)\] When the above reaction occurs, the entropy

    A)  remains same  

    B)  decrease           

    C)         increases           

    D)         none of the above

    Correct Answer: C

    Solution :

    On occurrence of                 \[N{{H}_{4}}Cl(s)\xrightarrow{{}}N{{H}_{3}}(g)+HCl(g)\] In above reaction, the disorder increases with the formation of \[N{{H}_{3}}\] and\[HCl\]. Therefore entropy increases.
