Given,

NO_{2} ⇌ \frac{1}{2} N_{2} + O_{2}

K_{1} .. (i)

N_{2} O_{4} ⇌ 2 N O_{2}, K_{2} .. (ii)

Required reaction

N_{2} + 2 O_{2} ⇌ N_{2} O_{4}, K

...(iii)
By squaring Eq. (i) we get,

2 NO_{2} ⇌ N_{2} + 2 O_{2}, K_{1}^{2}

...(iv)
Now, Eq (iii) is obtained by inverting Eq. (ii) and Eq. (iv) and by adding them as.

N_{2} + 2 O_{2} 2 NO_{2} ⇌ 2 NO_{2}, ⇌ N_{2} O_{4}, \frac{1}{K _{1}^{2}} \frac{1}{K _{2}}

N_{2} + 2 O_{2} ⇌ N_{2} O_{4}, \frac{1}{K _{1}^{2}} + \frac{1}{K _{2}}
