The Correct Option is A
Solution and Explanation
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.

- The reactions \(A \xrightarrow{k_1} B\) and \(C \xrightarrow{k_2} D\) follow first order kinetics. At \(500\,\text{K}\), rate constants are \(k_1\) and \(k_2\) respectively, where \(k_2 = 2k_1\). Activation energies \(E_{a1}\) and \(E_{a2}\) are related as \(E_{a2} = \dfrac{E_{a1}}{2}\). The rate constant for the first reaction at \(300\,\text{K}\) is half of its value at \(500\,\text{K}\). Given: half-life of first reaction is \(2\) hrs at \(500\,\text{K}\). Find the value of \(10 \times (k_2)_{300\,\text{K}\). }
