Nitrogen gas (N2) reacts with hydrogen gas (H2) to form ammonia (NH3). At 200
oC in a closed
container, 1.1 atm of nitrogen gas is mixed with 2.1 atm of hydrogen gas in an otherwise empty container.
At equilibrium, the total pressure is 2.2 atm. Calculate the partial pressure of hydrogen gas at equilibrium.

    Try this.
    ..........N2 + 3H2 ==> 2NH3
    initial...1.1..2.1......0
    change...-x....-3x......2x
    equil...1.1-x..2.1-3x...2x
    Ptotal = 2.2 = 1.1-x+2.1-3x+2x
    Solve for x and substitute into 2.1-3x for pH2. Something like 0.6 atm. for pH2.
