JEE (Advanced) 2022 Paper-1 - Question 51
Match the rate expressions in LIST-I for the decomposition of X with the corresponding profiles provided in LIST-II. $$X_s$$ and k constants having appropriate units.
| LIST-I | LIST-II |
|---|---|
| (I) rate = $$\frac{k[X]}{X_s + [X]}$$, under all possible initial concentration of X | (P)Â  |
| (II) rate = $$\frac{k[X]}{X_s + [X]}$$, where initial concentration of X are much less than $$X_s$$ | (Q)Â  |
| (III) rate = $$\frac{k[X]}{X_s + [X]}$$, where initial concentration of X are much higher than $$X_s$$ | (R)Â  |
| (IV) rate = $$\frac{k[X]^2}{X_s + [X]}$$, where initial concentration of X is much higher than $$X_s$$ | (S) |
(T)Â  |

| LIST-I | LIST-II |
|---|---|
| (I) Aniline | (P) Sodium fusion extract of the compound on boiling with FeSO$$_4$$, followed by acidification with conc. H$$_2$$SO$$_4$$, gives Prussian blue color. |
| (II) o-Cresol | (Q) Sodium fusion extract of the compound on treatment with sodium nitroprusside gives blood red color. |
