Which one of the following is a second order reaction?
- A \(\mathrm{H}_{2}+\mathrm{Br}_{2} \longrightarrow 2 \mathrm{HBr}\)
- B \(\mathrm{NH}_{4} \mathrm{NO}_{3} \longrightarrow \mathrm{N}_{2}+3 \mathrm{H}_{2} \mathrm{O}\)
- C \(\mathrm{H}_{2}+\mathrm{Cl}_{2} \stackrel{\text { sumlight }}{\longrightarrow} 2 \mathrm{HCl}\)
- D \(\mathrm{CH}_{3} \mathrm{COOCH}_{3}+\mathrm{NaOH}\)
\(\longrightarrow \mathrm{CH}_{3} \mathrm{COONa}+\mathrm{H}_{2} \mathrm{O}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{CH}_{3} \mathrm{COOCH}_{3}+\mathrm{NaOH}\)
\(\longrightarrow \mathrm{CH}_{3} \mathrm{COONa}+\mathrm{H}_{2} \mathrm{O}\)
Step-by-step Solution
Detailed explanation
The reaction is said to be of second order if its reaction rate is determined by the variation of two concentration terms of reactants
\[
\mathrm{CH}_{3} \mathrm{COOCH}_{3}+\mathrm{NaOH} \longrightarrow \mathrm{CH}_{3} \mathrm{COONa}+\mathrm{H}_{2} \mathrm{O}
\]
is an example of second order reaction.
\[
\mathrm{CH}_{3} \mathrm{COOCH}_{3}+\mathrm{NaOH} \longrightarrow \mathrm{CH}_{3} \mathrm{COONa}+\mathrm{H}_{2} \mathrm{O}
\]
is an example of second order reaction.
