STANDARD Chemistry Rate of Reaction MCQ Question

Type: MCQ-numerical-Medium-Class 12

Consider the reaction, 2N₂O₅ → 4NO₂ + O₂ In the reaction, NO₂ is being formed at the rate of 0.0125 mol L⁻¹ s⁻¹. What is the rate of reaction at this time?

A

0.0018 mol L⁻¹ s⁻¹

B

0.0031 mol L⁻¹ s⁻¹

C

0.0041 mol L⁻¹ s⁻¹

D

0.050 mol L⁻¹ s⁻¹

Correct Answer

Option B

Detailed Explanation

The rate of reaction is calculated as 14×d[NO2]dt=14×0.0125=0.0031 mol L−1 s−1\frac{1}{4} \times \frac{d[NO_2]}{dt} = \frac{1}{4} \times 0.0125 = 0.0031 \text{ mol L}^{-1} \text{ s}^{-1}.
