A rigid 10.0 L container at 298 K initially contains 0.500 mol of nitrogen gas and oxygen gas at a pressure of 0.800 atm. Then 2.00 g of hydrogen gas is introduced and the mixture is allowed to react according to 2 H₂ + O₂ → 2 H₂O. Assuming the reaction goes to completion, calculate (a) the total pressure in the container after the reaction and (b) the partial pressure of the water vapour formed.

Answer Options

A. 3.10 atm total pressure, 2.00 atm water vapour pressure
B. 2.85 atm total pressure, 0.95 atm water vapour pressure
C. 4.20 atm total pressure, 1.20 atm water vapour pressure
Correct Answer D. 3.65 atm total pressure, 1.60 atm water vapour pressure
Correct Answer
D
Correct Option:
3.65 atm total pressure, 1.60 atm water vapour pressure
