A) \[-107.36 kJ\text{ }mo{{l}^{-1}}\]
B) \[-4.44 kJ\text{ }mo{{l}^{-1}}\]
C) \[+107.36\,kJ\,mo{{l}^{-1}}\]
D) \[+4.44\text{ }kJ\text{ }mo{{l}^{-1}}\]
Correct Answer: D
Solution :
[d]\[\underset{Strong\,acid}{\mathop{HCl}}\,\xrightarrow{{}}\underset{(Complete\,\,ionisation)}{\mathop{{{H}^{+}}}}\,+C{{l}^{-}}\] | ...(i) |
\[N{{H}_{4}}OH\rightleftharpoons \underset{Weak\,base}{\mathop{NH_{4}^{+}}}\,+OH{{~}^{-}}\] \[\Delta H=x\,kJ\text{ }mo{{l}^{-1}}\] | ...(ii) |
\[{{H}^{+}}+O{{H}^{-}}\xrightarrow{{}}{{H}_{2}}O\] \[\Delta H=-55.90\text{ }kJ\text{ }mo{{l}^{-1}}\] | ...(iii) |
