MHT CET 2024 Chemistry question
For reaction product rate if reaction is . When and , calculate rate constant of reaction if reaction is first order in A and second order in B?
Answer: (C)
Solution
The rate law is . So . Units of a third-order constant: \dfrac{\mathrm{mol\,dm^{-3}\,s^{-1}}}{(\mathrm{mol\,dm^{-3}})^3} = \mathrm{mol^{-2}\,dm^{6}\,s^{-1}}.
