Given below are two statements:
Statement I: In a floral formula, \(\oplus\) stands for zygomorphic nature of the flower, and \( G \) stands for the interior ovary.
Statement II: In a floral formula, \(\oplus\) stands for actinomorphic nature of the flower, and \( G \) stands for the superior ovary.
In light of the above statements, choose the correct answer from the options given below:
LIST-I (Characteristic, feature) | LIST-II (Family) |
---|---|
A. Monoadelphous stamen | I. Malvaceae |
B. Cremocarp | III. Apiaceae |
C. Gynobasic style | II. Lamiaceae |
D. Capitulum | IV. Asteraceae |
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.
