Initially a flask contains nitrogen and hydrogen with a partial pressure of 0.3 atmospheres and 0.8 atmospheres. What will be the total pressure and partial pressure of nitrogen, hydrogen and ammonia after the following reaction is complete.
N2 +3H2--> 2NH3
[N2] | [H2] | [NH3] | |
Initial | 0.3 | 0.8 | 0 |
Change | -x | -3x | 2x |
Final | 0.3-x | 0.8-3x | 2x |
Hence [H2] will be the limiting reagent, so the value of x will be 0.8/3
Hence, pressure of NH3 will be 2 * 0.8/3 = 1.6/3 = 0.5333 atm
Pressure of [H2] = 0
Pressure of [N2] = 0.3 - 0.8/3 = 0.1/3 = 0.0333 atm
Total Pressure = [NH3] + [N2] = 1.6/3 + 0.1/3 = 1.7/3 = 0.5667
Partial Pressure of N2 = 0.0333 atm
Partial Pressure of NH3 = 0.5333 atm
