Question

Consider the reaction, N2(g) + 3H2 (g) leftharpoons 2NH3 (g) The equilibrium constant of the above reaction is KP. If pure ammonia is left to dissociate, the partial pressure of ammonia at equilibrium is given by(Assume that PNH3 < < P texttotal at equilibrium) (A) (3(3/2) K(1/2)P P2/4 )  (B) (3(3/2) K(1/2)P P2/16) (C) ( K(1/2)P P2/16) (D) ( K(1/2)P P2/4)

Correct answer is (b) (3(3/2) K(1/2)P P2/16)

Q. Consider the reaction,
$N_{2} (g) + 3 H_{2} (g) ⇌ 2 N H_{3} (g)$
The equilibrium constant of the above reaction is KP. If pure ammonia is left to dissociate, the partial pressure of ammonia at equilibrium is given by(Assume that $P_{N H_{3}} << P_{total}$ at equilibrium)

$\frac{3 ^{\frac{3}{2}} K _{P}^{\frac{1}{2}} P ^{2}}{4}$

$\frac{3 ^{\frac{3}{2}} K _{P}^{\frac{1}{2}} P ^{2}}{16}$

$\frac{K _{P}^{\frac{1}{2}} P ^{2}}{16}$

$\frac{K _{P}^{\frac{1}{2}} P ^{2}}{4}$

Correct answer is (b) $\frac{3 ^{\frac{3}{2}} K _{P}^{\frac{1}{2}} P ^{2}}{16}$
