Explanation:

The low boiling point and melting point of a covalent compound is due to their mutual sharing of electrons and their directional property on bonding compared to ionic as their tendency to gain and loose lather than sharing

Answer:

Covalent compounds have weak forces of attraction between the binding molecules. Thus less energy is required to break the force of bonding. Therefore covalent compounds have low melting and boiling point.

The equilibrium constant (K) : 11.85

<h3>Further explanation</h3>

Given

Reaction

N₂(g) + 3H₂(g) ⇒ 2NH₃(g)

Required

K(equilibrium constant)

Solution

The equilibrium constant (K) is the value of the concentration product in the equilibrium

The equilibrium constant based on concentration (K) in a reaction

pA + qB -----> mC + nD

$\tt K=\dfrac{[C]^m[D]^n}{[A]^p[B]^q}$

For the reaction above :

$\tt K=\dfrac{[NH_3]^2}{[N_2][H_2]^3}\\\\K=\dfrac{0.1^2}{0.25\times 0.15^3}\\\\K=11.85$
