Question

Consider the reaction,
$N_2(g) + 3H_2 (g) \rightleftharpoons 2NH_3 (g)$
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_{NH_3} < < P_{\text{total}} $at equilibrium)

• A. $\frac{3^{\frac{3}{2}} K^{\frac{1}{2}}_{P} P^{2}}{4 } $
• B. $\frac{3^{\frac{3}{2}} K^{\frac{1}{2}}_{P} P^{2}}{16}$
• C. $\frac{ K^{\frac{1}{2}}_{P} P^2}{16}$
• D. $\frac{ K^{\frac{1}{2}}_{P} P^2}{4}$

Answer 1

Answer: (B)

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