Question

A flask is filled with 1.08 atm of oxygen gas and 0.88 atm of ammonia and the following reaction is allowed to come to equilibrium in the closed container.

4 NH(g) + 5 O 2 (g) <==> 4 NO (g) + 6 H 2O (g)

At equilibrium the pressure of O 2 is determined to be 0.38 atm. Calculate the pressure H 2O at equilibrium.

A. 0.140 atm
B. 0.840 atm
C. 2.28 atm
D. 0.456 atm
E. 3.50 atm
