Question

Match the reactions of the List I with the relations in the List II.

Answer 1

We have, $K_P=K_C{\left(RT\right)}^{△n}$

So, (I) $H_2\left(g\right)+I_2\left(g\right)\rightleftharpoons 2HI\left(g\right)$

$\Rightarrow K_P=K_C{\left(RT\right)}^{2-1-1}=K_C{\left(RT\right)}^0=K_C$

(II) $N_2\left(g\right)+3H_2\left(g\right)\rightleftharpoons 2{NH}_3\left(g\right)$

$\Rightarrow K_P=K_C{\left(RT\right)}^{2-1-3}=K_C{\left(RT\right)}^{-2}$

(III) ${PCl}_5\left(g\right)\rightleftharpoons {PCl}_3\left(g\right)+{Cl}_2\left(g\right)$

$\Rightarrow K_P=K_C{\left(RT\right)}^{1+1-1}=K_C\left(RT\right)$

(IV) ${NH}_{4}HS\left(s\right)\rightleftharpoons {NH}_3\left(g\right)+H_{2}S\left(g\right)$

$\Rightarrow K_P=K_C{\left(RT\right)}^{1+1-0}=K_C{\left(RT\right)}^2$
