How are metal-carbon bonds (M-C) formed in metal carbonyls?

The value of K꜀ is 64 at 800 K for the reaction
N₂(g) + 3H₂(g) ⇌ 2NH₃(g)
The value of K꜀ for the following reaction is:

Which one of the following statements is not true?

The average molar mass of chlorine is 35.5 g mol⁻¹. The ratio of ³⁵Cl to ³⁷Cl in naturally occurring chlorine is close to:

For a reaction,
4M(s) + nO₂(g) → 2M₂Oₙ(s),
the free energy change is plotted as a function of temperature. The temperature below which the oxide is stable could be inferred from the plot as the point at which

At 20.0 mL solution containing 0.2 g impure H2O2 reacts completely with 0.316 g of KMnO4 in acid solution. The purity of H2O2 (in %) is (mol. wt. of H2O2 = 34; mol. wt. of KMnO4 = 158 )

The osmotic pressure of a solution of NaCl is 0.10 atm and that of a glucose solution is 0.20 atm. The osmotic pressure of a solution formed by mixing 1 L of the sodium chloride solution with 2 L of the glucose solution is x * 10⁻³ atm. x is (nearest integer)

A 100 mL solution was made by adding 1.43 g of Na₂CO₃ · xH₂O. The normality of the solution is 0.1 N. The value of x is (The atomic mass of Na is 23 g/mol )
