For the thermal decomposition of \( N_2O_5(g) \) at constant volume, the following table can be formed, for the reaction mentioned below: \[ 2 N_2O_5(g) \rightarrow 2 N_2O_4(g) + O_2(g) \] Given: Rate constant for the reaction is \( 4.606 \times 10^{-2} \text{ s}^{-1} \).

Choose the correct sets with respective observations:
(1) \( \text{CuSO}_4 \) (acidified with acetic acid) + \( K_2\text{Fe(CN)}_6 \) (neutralized with NaOH) → Blue precipitate
(2) \( 2\text{CuSO}_4 \) + \( K_2\text{Fe(CN)}_6 \) → Blue precipitate
(3) \( 4\text{FeCl}_3 \) + \( 3\text{K}_4\text{Fe(CN)}_6 \) → \( \frac{1}{2}K_4\text{Fe(CN)}_6 \)
(4) \( 37\text{Cl}_2 \) + \( 2\text{KFe(CN)}_6 \) → 6KC1
In the light of the above options, choose the correct set:
Given below are two statements:
Statement (I): In octahedral complexes, when \( \Delta_o < P \) high spin complexes are formed. When \( \Delta_o > P \) low spin complexes are formed.
Statement (II): In tetrahedral complexes because of \( \Delta_t < P \), low spin complexes are rarely formed.
In the light of the above statements, choose the most appropriate answer from the options given below:
Which one of the following options shows the correct evolutionary order of the plants mentioned below?
(i) Fern
(ii) Ginkgo
(iii) Zostrophyllum
(iv) Gnetales
