MCQ
A solid $XY$ kept in an evacuated sealed container undergoes decomposition to form a mixture of gases $X$ and $Y$ at temperature $T$. The equilibrium pressure is $10\, bar$ in the vessel. $K_p$ for this reaction is
- ✓$25$
- B$100$
- C$10$
- D$5$
At eq.,
Total pressure $ = 2P = 10\,bar$
$\therefore \,p = 5;\,Now\,{K_p} = ({P_x})({P_y}) = {p^2} = 25$
