A) \[\text{ }\!\!~\!\!\text{ 102}\,\text{k J}\]
B) \[-0.8\text{ kJ}\]
C) \[0.8\text{ kJ}\]
D) none of these
Correct Answer: D
Solution :
Key Idea: Heat of neutralization of strong acid by strong base is constant. But for weak acid or weak base it is less than constant value because some heat is required to dissociate weak acid or weak base. \[\text{C}{{\text{H}}_{\text{3}}}\text{COOH}\]is weak acid. \[\text{N}{{\text{H}}_{\text{4}}}\text{OH}\]is weak base. Heat of neutralization of \[\text{C}{{\text{H}}_{\text{3}}}\text{COOH}\,\text{+}\,\text{N}{{\text{H}}_{\text{2}}}\text{OH}\]cannot be calculated without the data about dissociation constant of \[\text{C}{{\text{H}}_{\text{3}}}\text{COOH}\]and \[\text{N}{{\text{H}}_{\text{4}}}\text{OH}\text{.}\]You need to login to perform this action.
