Answer 1

K = 2.3 × 10⁵ L mol^-1 s^-1

For order of reaction,

The general formula for the unit of k is mol^1-n L^n-1 s^-1

The unit of rate constant \(=\frac{\mathrm{mol} \mathrm{L}^{-1}}{\mathrm{~s}} \times \frac{1}{\left(\mathrm{~mol} \mathrm{~L}^{-1}\right)^n}\)

The unit ‘L mol^–1 s^–1’ corresponds to the 2nd-order reaction.
