Consider the reaction
N2(g) + 3H2(g) $$\rightleftharpoons$$ 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 << Ptotal at equilibrium)
5.1 g NH4SH is introduced in 3.0 L evacuated flask at 327ºC. 30% of the solid NH4SH decomposed to NH3 and H2S as gases . The Kp of the reaction at 327oC is (R = 0.082 L atm mol–1 K–1, Molar mass of S = 32 g mol–1 molar mass of N = 14 g mol–1)
A
0.242 $$ \times $$ 10$$-$$4 atm2
B
1 $$ \times $$ 10–4 atm2
C
4.9 $$ \times $$ 10$$-$$3 atm2
