Match the following
List - 1 (Items) | Matching | List - 2 (Products) |
A B C D | Vitamins A & D Shagreen Fish guano Isinglass | I.Dried skin of sharks II.Scrap fish III.Swim bladders of cat fishes IV.Fish liver oil V. Meat of fish |
Step 1: The correct matching for each item is as follows:
• A: Vitamins A & D are found in Fish liver oil (IV).
• B: Shagreen is associated with Dried skin of sharks (I).
• C: Fish guano corresponds to Scrap fish (II).
• D: Isinglass is used for Swim bladders of cat fishes (III).
Thus, the correct pair is A-IV, B-I, C-II, D-III.
Observe the following data given in the table. (\(K_H\) = Henry's law constant)
Gas | CO₂ | Ar | HCHO | CH₄ |
---|---|---|---|---|
\(K_H\) (k bar at 298 K) | 1.67 | 40.3 | \(1.83 \times 10^{-5}\) | 0.413 |
The correct order of their solubility in water is
For a first order decomposition of a certain reaction, rate constant is given by the equation
\(\log k(s⁻¹) = 7.14 - \frac{1 \times 10^4 K}{T}\). The activation energy of the reaction (in kJ mol⁻¹) is (\(R = 8.3 J K⁻¹ mol⁻¹\))
Note: The provided value for R is 8.3. We will use the more precise value R=8.314 J K⁻¹ mol⁻¹ for accuracy, as is standard.
