Match the rate expressions in LIST-I for the decomposition of $X$ with the corresponding profiles provided in LIST-II. $X_{\mathrm{s}}$ and $\mathrm{k}$ are constants having appropriate units.

List-I List-II
(I) rate $=\frac{\mathrm{k}[\mathrm{X}]}{\mathrm{X}_{\mathrm{s}}+[\mathrm{X}]}$

under all possible initial concentrations of $\mathrm{X}$
(P) JEE Advanced 2022 Paper 1 Online Chemistry - Chemical Kinetics and Nuclear Chemistry Question 7 English 1
(II) rate $=\frac{k[X]}{X_{s}+[X]}$

where initial concentrations of $X$ are much less than $X_{s}$
(Q) JEE Advanced 2022 Paper 1 Online Chemistry - Chemical Kinetics and Nuclear Chemistry Question 7 English 2
(III) rate $=\frac{k[X]}{X_{s}+[X]}$

where initial concentrations of $\mathrm{X}$ are much higher than $X_{s}$
(R) JEE Advanced 2022 Paper 1 Online Chemistry - Chemical Kinetics and Nuclear Chemistry Question 7 English 3
(IV) rate $=\frac{k[X]^{2}}{X_{s}+[X]}$

where initial concentration of $X$ is

much higher than $\mathrm{X}_{\mathrm{s}}$
