Q2:

Equilibrium constants K₁ and K₂ for the following equilibria

$\begin{array}{l} NO (g) + \frac{1}{2} O_{2} \overset{K_{1}}{⟶} {NO}_{2} (g) and \\ 2 {NO}_{2} (g) \overset{K_{2}}{⇌} 2 NO (g) + O_{2} (g) \end{array}$

are related as:

1. $K_{2} = \frac{1}{K_{1}}$

2. $K_{2} = \frac{K_{1}}{2}$

3. $K_{2} = \frac{1}{K_{1}^{2}}$

4. $K_{2} = K_{1}^{2}$
