Question

Which among the following is an example of a zero order reaction?

• A. Decomposition of N\(_2\)O in presence of catalyst
• B. Inversion of C\(_{12}\)H\(_{22}\)O\(_{11}\)
• C. Hydrolysis of CH\(_3\)COOCH\(_3\)
• D. Decomposition of N\(_2\)O\(_5\)

Hint:

Zero-order reactions have a rate that is independent of the concentration of reactants.

Answer 1

The Correct Option is A

Step 1: Understanding zero-order reactions.
A zero-order reaction has a rate that is independent of the concentration of reactants. The decomposition of N\(_2\)O in the presence of a catalyst is a typical example of a zero-order reaction, where the rate is constant and independent of the concentration of the reactant.
Step 2: Analyzing the options.
(A) Decomposition of N\(_2\)O in presence of catalyst: This is correct. This is a zero-order reaction where the rate is constant and does not depend on the concentration of N\(_2\)O.
(B) Inversion of C\(_{12}\)H\(_{22}\)O\(_{11}\): This is incorrect. The inversion of sucrose is a first-order reaction.
(C) Hydrolysis of CH\(_3\)COOCH\(_3\): This is incorrect. Hydrolysis of esters is typically a second-order reaction.
(D) Decomposition of N\(_2\)O\(_5\): This is incorrect. The decomposition of N\(_2\)O\(_5\) is a first-order reaction.
Step 3: Conclusion.
The correct answer is (A) Decomposition of N\(_2\)O in presence of catalyst.
