Question

The equilibrium constant for the reversible reaction, $N_{2}+3H_{2} \rightleftharpoons 2NH_{3}$ is K and for the reaction $\frac{1}{2}N_{2}+\frac{3}{2}H_{2}\rightleftharpoons NH_{3}$ the equilibrium constant is $K'.K$ and $K'$ will be related as

• A. $K=K'$
• B. $K'=\sqrt{K}$
• C. $K=\sqrt[\cdot]{K'}$
• D. $K\times K'=1$

Answer 1

Answer: (B)

$K' =K^n ;$ Hence $n=\frac{1}{2}$
$\therefore K' =K^{1/2}=\sqrt{K}$
